Yes. That's only a very basic implementation.

The SSL relocation server will not do client cert verification and there's
no way to configure the client to use specific cert right now.

I think SSL cert verification could be a way for security. But you need distribute
the certs to all the servers in a pool and reload xend relocation server to
use the new certificate.

Thanks,

Zhigang
