[Twisted-Python] Question about XMLRPC, Sync and ASync

Hi everyone.

I'm relatively new to Twisted, though I have used parts of it for a while.

What I'm trying to do now has me a little stumped -- I have two servers,
one of which answers XMLRPC requests, and it calls another one using the
twisted basic.LineReceiver system.

So I have an incoming XMLRPC request, and I need to issue a command to
the other server and wait for it to come back before I respond to the
xmlrpc call. So I'm trying to do an async call inside a synchronous call.

I think that deferreds will play a part here, but I guess I must be
missing something, as I'm not sure how to proceed. Can I return a
deferred from my XMLRPC handler? And if so, how do I fire the callback
when the result comes in to the LineReceiver?

Thanks,
   Colin
