io.sockets.to('room').emit() needed

[jakeg]

You can io.sockets.emit('foo', 'bar') to send a send a message to everyone from outside of an individual socket. But what if you want to send a message to everyone in one room only from outside of an individual socket? Something like io.sockets.to('room').emit('foot', 'bar')

Use-case would be polling a database for updates and sending them to everyone in one room only. You don't want every single client in that room doing their own database poll.

io.sockets.in('room').emit('foot', 'bar')
