[Twisted-Python] Both pb.Copyable and pb.RemoteCopy: How to use?

[Steve Freitas]

Hi all!

I'm plugging through the pb docs, and a note says that if you want to send an 
object over the wire in either direction, just make the desired class inherit 
from both pb.Copyable and pb.RemoteCopy. That's cool. But, what to do after 
that? Meaning, only the sender can grab a root object (pb.Root), and so only 
the sender can send jellyable objects out.

I realize one answer to this would be to run a server on both sides, but I'm 
in the situation where my client can contact my server, but not the other way 
around. So, is it possible for the sender to contact the receiver, and then 
for them to start swapping objects willy nilly? (Note that the next place I'm 
going to take this is pb.Cacheable, so beware. :-) )

Thanks!
