Fair enough. I get your point about the binary transport over IP. And since there's \
no compelling reason to mix and match it makes sense not to certify it, who knows \
what gremlins are in there, even though no one has discovered any.

Thx,

Not unless the protocol were HTTP.

Keeping non-trivial C++ code compiling portably between 32 and 64 bit is a
huge effort, and for various reasons I didn't think the numeric data
passing across would stay intact and I never tested it. Nobody who's tried
it has experienced any problems, but I'm not going to spend my time trying
to support that, not with everything else I have to deal with.
