I don't remember exactly what was in there, but I certainly did this, and Ali's PhD thesis did this (been that long?) :) There is code in the tree for grabbing the stack for the guest process. One could also do something using the remote debugger stuff, though I'm not sure anyone ever used that in SE mode.
