Never is... A big word
When I have more structual stuff done for repo.sc, we can definetly revisit the idea of foreign sources and newly appeared/unteusted sources.

One partiularly big problem we have right now is that a down'ed source can cause delay for other sources to update. For example, for the last week or so, I've been having a hardtime accessing iphone.org.hk repo from both home and server, as such it caused delays in the update script, because curl timeout is not handled by an exception catcher that I've incorrectly implemented... Ive fixed the bug now, I think, but I can't really test it properly until another source goes down... And we don't want that now, do we? (no, we don't)

When the infrastructure is setup properly, to handle down'ed sources and stuff, we can look into possibilities of "anti-virus" for packages, which I already have an idea for, and them we can allow people to contribute sources freely. But that's still quite a bit to go, so please bare with me in the mean time

On a side semi related note, it would seem that iappcat is a little bit ahead of us on this aspect, as their tracker can track server outages and things of that nature... I should rush through my school project and get right back coding here to catch up, hehe.
