Is a Sponge client mod even possible?

Being able to have sponge on both the server and the client, and thus allowing for some native server client communication in vanilla and forge servers would be pretty awesome. I haven’t found a good way to make sponge work as a client mod exactly since it seems that it really has been made for servers, even though there are some methods that ask if it’s a client. Is there anything to what I’m suggesting?

I’m not sure what you’re asking for Sponge to do on the client… It works the exact same way as on a server, just that it doesn’t have other clients connected. Plugins will still work just fine on the client as well as on the server.

I’m talking about interacting with client specific features, really.

AFAIK that’s in the roadmap but currently not a priority

Is there a link?
