### Original description

I'm guessing this is because we can't return a Client from it, and we're trying to avoid pointers or references. Maybe we can return a ClientProxy class or something, which also inherits from Client and basically wraps a pointer to a EthernetClient (or other subclass of Client)? Or even make the Client base class itself also able to act as a proxy?

What do you think, Adrian? Want to bring it up on the developers list?
