Hmmm, not an externally accessible one - there is one for internal deployment of widgets that Chumby authors, but it's all behind the firewall.

I'll put it on the list of things to do.

Obviously, we'd have to create a system that prevents abuse - ie. automated creation of thousands of accounts and uploads of thousands of widgets in order to DDOS the system.

We already having people doing automated spamming of this forum and our wiki - we really want to protect the chumby widget system from similar abuses.
