Personally, if I was interested I would think twice now.
I wouldn't blame anyone for feelign that way, but I wouldn't think twice personally. If it hadn't been Antony ( assuming it even is, and frankly, I just assumed all along it would be ) it would have been someone I didn't know at all, so I really wouldn't have had any trust in a stranger anyway. I would have been putting my trust in the people standing behind the project, which is Evak and Cygnus. Who they choose to use as freelance talent is up to them, and I don't think anyone has any doubts about Antony's skills as a programmer anyway.
Now that said, I already have a mature 3d engine, and I'm not seriously considering Flow ( except maybe to play around with, I do own a few 3d engines just for larks ) so I can't say for certain I wouldn't feel differently if I wanted to actually develop something with it. But Evak and Cygnus both have a good name around here, so I don't think it would affect me.
