Question: Is it possible to create an VPN connection while using site-to-site VPN?

Have you ever tried or done this?

What are possible problems, pitfalls, things of the impossible, etc. ?

Answer: 
Yes.

Either you use e.g. "screen" and customize it:

Or you manage to do it on your SSH Client, if possible.

I was just looking for the same thing and found this article:

<http://akrabat.com/php/osx-terminal-colours/>

It uses a php script to change the terminal colors by applescript. You can set up mappings of different colors for each server. Works great for me, though feel the urge to rewrite the php stuff into ruby :)
