In addition to the other suggestion (use NFS, which I have been doing with
great success) you can use squid, which will cache both FTP and HTTP.
Squid won't do what you want out of the box, however, and neither will
fetch. Two things to do (in order)
1. Make sure fetch knows to use the proxy. The man page tells you how to
do this. I believe you set an environ, but I'm not sure, read the man.
2. Make sure your proxy server will cache very large files. Squid refuses
to cache very large files by default, and I'd guess other proxy servers
do the same. Squid can be configured, however, to cache files no matter
how large they are. On the proxies I've installed, this tweak has
been a good idea. Just make sure you have enough disk space to cache
all that stuff.
