Had an idea - looking for a math buff to tell me if it's possible with today's technology.

Wildly off-topic for the NANOG mailing-list, as it has -zero- relevance to
'network operations'

I have, on my computer, an encoder/decoder that does _exactly_ that.
Both the encoder and decoder are _amazingly_ fast -- as fast as a file copy,
in fact.
the average size of the tranmsitted files, across all possible input files
is exactly 100% of the size of the input files. (one *cannot* do better
than that, across all possible inputs -- see the 'counting' problem, in
data-compression theory)

'Weird' is one word for it. You might want to read up on the subject
of 'data compression', to get an idea of how things work.
See also "polynominial curve-fitting", for the real-world limits of your
theory.
