I've researched this and couldn't find anything on it.
I'm sure you all know when you have too many sources, you get the "bla, bla, WOW! You've exceeded the number of package names this APT is capable of."
Well, I was thinking..(maybe I shouldn't do that) and said, "Why can't Cydia have several different "master lists", each with several repos in them?"
You tell Cydia which list you want to use, and it loads that list with certain repos on it. This would do away with the above error that I think everyone with a jailbroken device experiences + give the public access to a lot more stuff.
Has anyone heard if a tweak like this is out there? I would imagine saurik himself would have to integrate it into Cydia.
Let me know what you think.
