you are limited by 1G (tested) or about 1.5G (max) rvm on a 32-bit
architecture. So you would have to run about 50 server processes on each
server host to be able to hold all of your data.
Then your setup will be of course a less trivial one, forcing you into
balancing the data between the servers, I mean server processes, not the

It depends though on the average size of your files, the bigger the files,
the more data you can afford. On the other side see Jan's yesterday notes
about dubious usefulness of big files on Coda.

If you have done make client-install, you have got the client, too.
You don't have to run a client on server hosts.

The messages above, below [***], are just a hint what to do on a client

The messages above, above [***], are a manual way of starting coda server,
provided all of the binaries are on your path.

I am afraid you may find Coda too burdensome to setup for your data
amounts. It would be more than an order of magnitude over the biggest Coda
setups ever existed (IIRC).
