I found a homepage of one guy who made himself carbon fiber and now also bamboo MTB frame. It is one of the most amazing things I have ever seen, so if you want to see it, have a look at http://www.bme.szm.sk.
It's beautiful! I like to innovate too, so hurray for him if it works.
I sure hope it isn't a punji stick waiting to happen. If there's a problem in that regard, he might consider wrapping it in a tough material that would contain any broken ends.
