Actually my current implementation is 'in-order' on the reliable
side. I put incomming messages into an input buffer, but the app
only gets fed them when they are in-order with no gaps. I think its
quite important to have this property as I want things like chat
messages to appear in the order they were sent to you. Frankly the
amount of traffic in the reliable channel should be dwarfed by the
non-reliable.

The non-reliable channel is not in order.
