If you had a thorough look at Daniels work you should have noticed, that
he carefully did choose the "enet" networking lib. Enet provides TCP
features like connections, sequencing and reliability on UDP. By
limiting the transfer to event data only none of the problems above
should occur.

Of course a lot of work has still to be done. Starting with an 
architecture independent data encoding, time synchronization, ...

and Enigma itself? Please provide us all information you have.
