The storage-server side of Tahoe doesn't really do that much, so I'd be
pleased as punch if it could fit into 10 or 20MB. To do that, I think
we'd need to avoid loading all of the code when we're not running a
client (I'm thinking zfec, pycryptopp, twisted.web, conch, ftp/sftp).
Switching away from foolscap (to HTTP) might help too (or might hurt, if
the crypto needed to replace it is actually bigger).
