I kind of already implied all that.  Even if they are (for whatever
reason) totally against installing a new protocol (there have been some
rsyncd security issues recently), publishing the data as both 80mb file
and daily diffs is a no brainer and would accomplish much of the bandwidth
savings of rsync...just requiring a little more work at the remote ends to
download the right diff(s) and apply them.

Diff and patch are also available for these platforms.

I wonder though, are there any compelling reasons for ARIN not to release
bulk whois data in more useful formats, such as might be more directly
usable to setup local whois mirrors?
