They do not take into account things like endianness into

I think we all agree that we need a TCP interface.
No. In my implementation I think I have shown that you can run your
cluster with a much more minimal network-interface.
My current implementation is less than 100 lines of network-facing code
(using ICMP payloads, but the same could be achieved with UDP), though
that increases to about 300 if you count in the SHA-1 implementation
that I am using for verifying customer credentials. So 300 lines is for
a complete solution including crypto and accounting/payment.
My nodes answer ARPs and pings, but that is all.
