Binary is fine. Uncooked memory is not. :) And FWIW, XDR seems awfully heavyweight to me. It involves a comparatively large amount of code for things that are really pretty easy, while at the same time making hand optimization of the packet format more difficult. Note that this hand tuning can be really beneficial, especially if the server is on a low bandwidth link. The multiplayer protocol I was thinking of (which these days is, I guess, mostly an idea box for the working version) managed to pack a full precision* position, velocity, acceleration, orientation and rotation rate into a block of 26 bytes. * Positions to within 1mm, orientations to within a degree over a typical inter-packet delay. That's about 3x smaller than a naive implementations based on floats and doubles, which means that you can transmit data on 3x as many aircraft/objects over the same link.
