   Some services (SKYDRIVE) which purpose virtual drive mapping does not accept than her product is a real remote drive (to avoid temporary traffic as temporary files, classical example is OpenOffice softwares loads some temp files during edition in the same directory) so they are an easy method to test if your virtual drive is on this case:
On a real HD this easy test batch below only create one file named "it_s_ok.txt" on "vivilproject-testdrive" directory: if you do not see ONLY this file on the directory, your remote dir is not a real virtual directory but only a gateway ;)
                                    test.bat
rem z:
rem cd \SKYDRIVE
md vivilproject-testdrive
cd vivilproject-testdrive
cd ..
rd /S /Q vivilproject-testdrive
md vivilproject-testdrive
cd vivilproject-testdrive
echo one.one > one.one
rename one.one one.two
move one.two three.two
copy three.two > it_s_ok.txt
del three.two

Now this is the AUTOHOTKEY script to automatically launch OPENVPN sessions...
do not forget to see the common warnings too ;)
--------------------------------------------------------------------------------
#Persistent
SetTimer, EnterAuth, 250
return

EnterAuth:
Process, wait, openvpn-gui-1.0.3.exe, 2
If %ErrorLevel% = 0
{
Run, c:\Progra~1\OpenVPN\bin\openvpn-gui-1.0.3.exe --connect YOUR_OVPN_FILE.ovpn
}

IfWinExist OpenVPN - User Authentication
{
WinActivate, OpenVPN - User Authentication

ControlSetText, Edit2, YOUR_PASSWORD, OpenVPN - User Authentication ahk_class #32770
ControlSend, Edit1, {Enter}, OpenVPN - User Authentication ahk_class #32770
}
return
--------------------------------------------------------------------------------

Now this is the method to launch OPENVPN on Windows as a service...
3 conditions:
1a) You must use an OpenVPN build with "-enable-password-save" option. (http://www.acevpn.com/2009/12/07/openvpn-build-with-save-password-enabled/)
2) Keep only ONE KEYSET on the "config" directory ! (usually the .crt file and one .ovpn file)
3) In the .ovpn file change "auth-user-pass" to "auth-user-pass foo.txt"

FYI i have noticed the VPN connexion only works again after 2/3 minutes if an hang-up occurs (IP renewing, ISP disconnection, you unplug modem by error...)
do not afraid during this time no core traffic is transferred by your real IP :)
do not forget to see the common warnings too ;)
--------------------------------------------------------------------------------
net stop openvpnservice
c:\progra~1\openvpn\bin\openvpnserv -remove
c:\progra~1\openvpn\bin\openvpnserv -install
echo YOUR_USERNAME> c:\progra~1\openvpn\config\foo.txt
echo YOUR_PASSWORD>> c:\progra~1\openvpn\config\foo.txt
net start openvpnservice
del c:\progra~1\openvpn\config\foo.txt
--------------------------------------------------------------------------------

COMMON WARNING: NEVER FORGET THIS BATCH IS NOT LAUNCHED AT THE BOOT !!!
To detect "on the fly" what is your actual IP, you can use a batch thanks to curl and this php script on a webhoster:
I offer you the php script, build yourself the batch ;)
* (DynIP) if myIP contains "." *AND* does not contains ".dyn.myisp.com" then launch...
* (FixedIP) if myIP is not " 93.251.200.56 " then launch...

<?php echo " ";
echo $_SERVER["REMOTE_ADDR"];
$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);
echo " ";
echo $hostname; echo " ";

How to inscrease cronjobs to create regular cronjobs of less than 1 minute ?
Solution is given by a cronjob hoster, thanks to him ;)
--------------------------------------------------------------------------------
<?php
# script to increase cronjobs to less than 1 minute
# Offered by SETCRONJOB
  // Cron settings
  $cron_url="http://yoursite.com/path/to/cron.php"; // Cron URL here.
  $time_interval=20; // Time interval needed (second).
  $real_time_interval=1; // Real time interval (minute).


  set_time_limit(0);
  ignore_user_abort(1);

  $number_of_execution=floor($real_time_interval*60/$time_interval);
  for($i=0; $i<$number_of_execution; $i++) {
    $time=microtime(1);
    file_get_contents($cron_url);
    $time=microtime(1)-$time;
    $i<$number_of_execution and sleep($time_interval-$time);
  }
?>

Some services refuse you change their default directory ("My Dropbox" is a well-known example, they are others methods to bypass this:
W7, VISTA:mklink /J "C:\Users\YOURNAME\Documents\Dropbox\DesiredFolder" "C:\Path\To\Desired\Folder"
XP:fsutil hardlink create "C:\Path\To\Desired\Folder" "C:\Documents and Settings\User\My Documents\My Dropbox\DesiredFolder"
DROPBOX GUI or other generic method for others OSes are here.
