Hehe, alpha? Not even that I guess. As I see it, the problems are
a) that noone is working on it
b) that an integration of v4 and v6 is missing: you can only use either 
v4 or v6, not both at a time and
c) the v6 implementation seems to just be packing/unpacking of level 7 
datagrams, which is far from a total and usable implementation of v6

So in my opinion, there is far more to do than expected from 'alpha'... 
Any help is of course welcome!
