Thanks, Brad.  Now that you mention it, I do have some FAQish questions
that I didn't see answers to after a quick scan of the web site and list
archives.  Sorry if they're remedial but I just learned about memcache (on
the mod_perl list) and wanted to get a basic idea of what it does and how
it works:

1) It looks like the client initializes with a list of servers it knows
about, how do those servers communicate with each other (assuming they do)
so they stay consistent with each other?

2) Assuming the servers have some mechanism to stay in sync, is there a
way to clear the cache across all of them and start from a clean

3) I can see why you'd run memcache daemons on multiple machines, but what
would be the motivation for running more than one daemon on a single
