Hey, sorry for the late reply.
I am not sure what you mean. Do you mean you want to proxy your cilent through a hydrus server, so that web requests go through the server? Or do you mean you want to send your normal searches to a server, and not have a local cache on your client?
At the moment, neither of these things can be done. I think I can add a proxy system without too much trouble, but the network has been built from the ground up for local cache searching, so it would be difficult to alter that.
