Greetings!  Bureaucrats and other network illiterate types are demanding to
run NFS traffic over a T1 between campuses (about a 6 mile run).

This link is already congested with LAT, LAST, FTP, and DECENT traffic.
Well, not really congested, about 10-20% utilized.

Since NFS is UDP based, I *know* that it is not a "good idea" to run 
it over low bandwidth lines, but I need references, testimonials, etc. so 
that I can present my case without having to "burn to learn."

Also, if there are ways to sanely do NFS over slow links, I am 
interested.  Kernel mods, secrets, tweaks, black art, all welcomed.

Another alternatibe is to install a >= 10 Mbit link in the form of
T3 or dedicated fiber/microwave.  The distance is about 6-7 miles.
We have bandwidth now, but will latency then be an issue?

We are using cisco routers on both ends of the link, so there is more
delay.

I am under the impression that NFS is for machines only in geographically
close proximity.  Correct me if I am wrong.

All tips, pointers, hints, flames, tweaks, twiddles, and frobs welcome.

I will post a summary if there is sufficient interest.
