I've used gnute and now mutella for a little more than two years in this manner.

One thing I'll add to the above post.

I use:

screen -r -d


To reattach to my session. It seems to always work. With mutella's web interface, I spend about 50% of the time managing it that way.

screen is a beautiful thing.

I've been running OpenSSH for the past several months. Along with a router port forwarding of 6346 to the mutella session.
