If you file bugs against the GTK+ bindings for TOM, I'd be happy to look into fixing them. I'm less enthusiastic about fixing the GNOME parts, but may be willing to fix that as well. Alternatively, I'd happily accept patches!
About the TOM VM, there is a TOM VM written. It hasn't been well tested due to the lack of a bytecode compiler. We'll get to that at some point. :) We're working on other TOM projects at the moment though, so it may take a while.
