On t-mobile's (USA) cheapest data plan, I can't seem to ssh back into my n900 by the IP. I'm thinking of having it ssh into my webhost and maintain a reverse ssh tunnel, so I can get into it that way. Also, it really shouldn't be hard to get the desktop linux dyndns client packaged. The only thing is having to use dbus-monitor or connler (both from maemo4, might need an update) to have the script run when the dbus message goes out that an inet connection was made.
