Another option is a ssh tunnel from each client to your server. If this
is feasible in your environment, it has the big advantage that your code
won't even now that the communication is encrypted, only the client
would have to connect to the tunnel.

Perhaps someone else can comment on secure sockets. Java has them,
and I'd expect your server to know how to deal with them, too.

I'd also ask on a Zope list.

Good luck,
