I believe the SDK is actually a chargeable product
It certainly was when I got hold of v6 (or was it v7?) a while ago - I blagged it as it used to be free and I was using that version. you might find people willing to loan it to you though!
The biggest problem I have is that error we were talking about. If you were to provide a way to get multiple (i.e. 6,7,8 etc) camera feeds onto a single ML page, spread around as per your 0019 scenes and at faster frame rates than 1 fps, I'd certainly be willing, for one, to pay for something.
I don't believe there's a way to do this currently (maybe with the streaming video beta solution???) - web lobby wont support that number of frames will it?
