I agree that it would be ideal to have just one way generic and extensible enough. I do not know if there are much difference in that area between the two approaches, though. The RFC I saw did look more complex and rigidly specified with framing and such, but that is only the syntax part---in the way in which interaction between two processes happen, I didn't quite see fundamental differences. I'd expect it wouldn't be too much trouble to add new commands to code written using either approach (although I haven't seen yours yet ;-).

Thanks.
