I've made a proposal to add ByteString based datagram communication to
Network.Socket and Network. Details are at:

http://hackage.haskell.org/trac/ghc/ticket/1238#preview

I rushed to get this done before I go on a trip tomorrow so I haven't
completed testing and won't be available to discuss it for the next 9
days. As such, if discussion is needed, an extended deadline would be
appreciated.

Testing windows is a bit awkward for me since I don't have a windows
machine, so if anyone can test that platform I'd be very appreciative.
I'll try to work through the problems I was having with hugs and test
when I get back unless someone else wants to test it first.

Thanks.
