I have once tried that, specifically with sshfs, too, and failed miserably.
Your zeroth approximation should be to factor out Gambas and write a shell
script which can pass the password to sshfs. If you've got that, you almost
have the solution in Gambas.

There is a program "expect" which was designed for specifically the purpose
of waiting on a program's output for a specific pattern and then sending a
given string to its input (i.e. to automate interactive programs). But it
seems sshfs is putting extra effort into preventing this automation.

I ended up creating a private/public key pair and have the server work with
that so that I can login using these keys[0]. Maybe this is an option for
you, too?

If you can trick sshfs into being automated via expect or some other means,
please let me know :-)

Tobi
