Windows: Right-click 'Send To' over SFTP
I created a batch file for windows that allows you to send any file to a remote computer over SFTP (file transfer over SSH) with putty... very basic stuff, but an idea that someone might find handy:

echo put %1 > myserver.psftp
echo exit >> myserver.psftp
"C:\Program Files\PuTTY\psftp" username@myserver.com -b myserver.psftp -bc

Then if make a shortcut to that in your 'send to' folder (c:\docs+settings\yourname\sendto) on 2k/xp normally, you have a two click operation to put any file from your filebrowser to your server.
