Right now thougt I'm thinking learning experience with zeromq, and also I'm seeing how I can build something that can be used to scale an http application beyond a single datacenter/cloud and more. I actually find that pretty exciting and since I have young children and a good paying job, I'm still treating the product I'm working on as a hobby rather than a business.
And who knows, maybe you'll do something better. That's progress.
Also check out gevent and eventlet to see the differences with those systems as well. I just submitted a patch to eventlet to give it better zeromq support.
