Is there anything like cydia for kindle?

I recently jailbroke my kindle and I mostly like it so far but I don't like having to get my computer whenever I want to install something. I was wondering if there was a store for the programs that not only puts it all in one place, but also lets me install them without my computer.

If there isn't, I will give a crack at making it because I don't think it would be that hard. All it needs to do is list the programs, download the packages and install them.
