This is what "information" means, in the entropic or information 
sense.  Compression science is about trying to find the smallest 
representation of the same information (or, in domain-specific cases like 
JPEG or MPEG, determining what information is OK to lose when the end 
processor will be a human brain).  What you're working on comes down to an 
efficient compression algorithm... and those already exist.  You can 
implement compression on a filesystem or over the wire regardless of 
format; it's not clear to me where the win is in precompressing.
