Sorry for not taking the time to read through the implementation, but I have 
another couple of questions:

- Is it possible to return an interface as an [out] parameter, receiving a 
proxy to a remoted object?

- Is it possible to pass an interface as an [in] parameter, having the 
receiver receive a proxy to the original object?

- Did you consider implement cross-process reference counted lifetime 
management (ala DCOM)?

- Did you consider specific support for cross-apartment marshalling (sorry 
for all DCOM terms, but that's what I've been using in the past)? That is, 
did you consider different threading models, so
that single threaded applications only would receive callbacks in the 
context of the main thread?

Lastly, are these implementations available in the download and, under what 
kind of license is the current implementation distributed (I'd like to try 
it out in a current in-house project)?
