32bit TZT - A possibility?

[Syntax]

It seems to me that the only flaw to TZT is the 16bit mode it has to run in. I get alot of color banding in alot of my clips. Now I'm no programmer but how much work would it take to make TZT able to run in 32bit mode? I would assume that we're talking about rewriting the entire program or something am I wrong? I would be more than willing to learn what I need to know in order to make this happen. Is it all pretty much C++?

Thanks and much props to all the peeps who have contributed to making TZT what it is today!
