The simplest solution when you want SSH logins to happen transparently 
in the background is to make a public key, install it on the server and 
then use the public key to login instead of your password. The benefit 
of this is that a program such as ssh-agent (Linux/Unix) or pageant 
(Windows) can ask for your password ONCE when you log in and then 
(effectively) securely hand it on to other programs that need it until 
you log out.

See e.g. http://mah.everybody.org/docs/ssh or 
http://the.earth.li/~sgtatham/putty/0.55/htmldoc/Chapter9.html for details.

I hope this helps,

Chris.
