There is a need for cache servers and distribution servers.  The
overall effeciency of the Internet would benefit from there use.
There would need to be a way to ensure that the data the server had
was current.  This could be accomplished by using "content signatures"
which are 64 bit numbers (32 bit filesize field + 32 bit crc field).
See the document FWKCS120.REF in the DOS Shareware program
FWKCS120.ZIP for information regarding "content signatures".

Existing client programs could take advantage of the cache servers by
making their queries through the servers.

But even if the data had changed it would be preferrable to just move
the changes across the Internet.
