Two remarks :

1 : the ssh program "ssh-askpass", (OpenSsh contains it), is an X program ; 
then calling "ssh -X .." might disable the ssh server to launch ssh-askpass.

2 : using an "ssh-agent" is, in my opinion, the best way to use ssh. Once the 
agent is loaded, a connection using ssh won't need to ask for a password. You 
can then, in Mathematica, connect to remote kernels or remote ibrairies, 
using ssh tranparently. OpenSsh provides the ability to use ssh agents.
