newt is right: using the Prof-UIS libs was a big mistake for us, because you have to pay for a license to use it (about �200 IIRC), which is an instant turn off to 99% of open source developers. We've fixed this in C2 which doesn't use any paid libs.
The Prof-UIS libs are used only in the editor - so third party developers can build the runtime and any of the plugins without paying anything - just not the editor.
I can set up a fundry for 0.x, but the Prof-UIS licenses would probably just kill it - $100 is half way to a license for one developer, without leaving anything to actually motivate the developer.
Also, the event sheet pasting issue could be completed, but it would probably be buggy even when done, due to the codebase issues outlined in the open letter. Also, $100 would pay for about five hours work reasonably, but I'd estimate there's at least 50 hours work in the job... and I'm kept pretty busy by university and developing C2, so I don't think I have time to take on the job myself.
Removing the Prof-UIS libs from 0.x is a rewrite level job which is basically being done already in C2!
Soo... that's the situation. Sorry if it's disappointing. It's a bit tricky. C2 is having this kind of thing built in from the start anyway - it will take a long time for C2 to catch up with 0.x in maturity, but the situation is basically the same as the open letter: 0.x is a huge mess, we're fixing things like this in C2, and we don't have time to do both. So we're pretty much cornered and I think the best way out is just go 100% with C2.
