[ENet-discuss] Broadcasting to multiple servers

Hi Ben,

I ran into this same issue. Currently the solution I am using is to drop
down to low level UDP on the servers to broadcast their network information.
Clients listen to this and are able to form a list of the servers on the
network, and initiate connections to them in a non-broadcast manner.

Not sure how to have a more enet-integrated solution to this issue (which
would be nice), but the issue (as far as I can tell) is that my enet-clients
only allow 1 connection, and so all the servers 'jump on that connection'
and whoever jumps quickest gets the slot...

So random thought that might cure: allow multiple connections on the client
might be a way to make this work (although I have not tried this yet..)

Let us know how it goes! :)
