[ENet-discuss] allocating lots of channels

You'd be using channels out of context to save a single char.
Channels are meant to differentiate types of packets that need a certain
ordering. For example, character health updates and chat messages. Both need
to get there reliably, but a health update doesn't need to wait for the
latest chat message to be there. So you'd use 2 channels to make this more
I would think adding the extra 'id' char is faster than letting ENet handle
the sorting/queueing for the extra channels.
