Before I got here at CMU I ran a coda-client _and_ server on a single 
16MB 486-66. Of course it was hardly usable, and a recompile cost me
at least 4 hours. But it was enough to play around with the system.

Effectively, for a client with a 200MB cache you would use about
20MB of (virtual) memory for the meta-data (RVM). So for an 8-16MB
machineI would advice to use a local cache between 40 and 80 MB. That
way startup and occasional internal cache-scans will be relatively
fast, because all the RVM data can be in memory at the same time.

If you start running things like X or big applications, most of
Coda's RVM data will be swapped to disk. However, the regular cache
scan's will cause more swapping than normal to occur.
