It's a pretty bold admission because customers "not caring about the underlying platform" means windows won't be the infection vector for all that other MS software. Maybe they're getting ready for a future when there are hordes of iOS and android devices out there. They have to do something to get people using their libraries and other software. I don't think anyone really believes that windows mobile or whatever mobile OS microsoft tries next will take over the market like back in the wintel days.

I may be working on just such a beast. Basically,
it's a server that hangs on a socket. Clients
connect and optionally identify themselves. A
client can send a message, via the server, to
any client which has identified itself. A client
can query the server for info. A client can
ask to snoop on one or more other clients or to
receive all messages of a certain type, or all
messages.

Is this what you mean by a message queue?
