Looking for info/tech article on passing FP over TCPIP.

It's going to be necessary for me to pass FP nummbers over a TCPIP connection. For now, it'll be between two or more windows machines, but eventually, I want to incorporate something universal (at least to include Linux/X11 and Windows).

UPDATE: Nevermind. After doing about six hours research, I guess it comes down to similar architectures can pass them back and forth quite liberally without mangling them.

Endianess is the biggest concern now that IEEE is the industry specification.
 
If all your processors are x86, I don't think there's much problem. There should be no endianness concerns.

On the other hand, if you want a real generic method, try MPI, the Message Passing Interface, or its Open relative. MPI takes a good deal of code overhead, but it lets just about any architecture talk to any other.

That won't be acceptable because the message passing will be relaying real time info so it needs to be efficient.
 
MPI is very efficient. It's used in supercomputers for internal communications. It's just not code-space-efficient (i.e. IMHO, it takes a lot of writing C code to get it working.)
