     While the use of a caching proxy is pretty cool, two cases come to
mind where caching proxies are suboptimal:

1. Performance. Over a slow/distant network link, it may take a while
   to populate/update the cache. With CVS, you can use cvsup or rsync
   (yuk) in a nightly cron job to get a read-only mirror; this way,
   during the day, local clients can access the read-only copy at full
   lan speed. With a caching proxy, the first client to hit the proxy
   can get a big performance hit, while the cache gets populated.

2. True disconnected operation (no LAN connection whatsover of any
   type). Caching proxies tend to insist on having a LAN connection ....
   ;-( In some cases, it's very nice to have a periodically-updated,
   read-only copy of a repository.
