So, summarizing:
1. MarkTraceur (and the Multimedia Team) is working on a way to do 'beta experiments' on live wikis that do not involve things being left to be Gadgets all the time. This can also eventually help 'promote' gadgets into Extensions / Core. 2. Tyler is working on an Extension for this (or it might already exist, as Krinkle pointed out)
So, is HotCat replacement extension going to plug into the Beta Experiments thingy Mark is working on? I suppose there'll be docs on that at some point of time...
