I think you may have mis-read my mail as I'm not suggesting we go the 
two sockets route. This needs to be fixed in the rsockets module but the 
timeframe on that isn't clear at this point. Yes, we could introduce 
factory methods that take a protocol family like we did in 
DatagramChannel (for multicast case) but it puts a burden on that usages 
that we also want to avoid.
