Btw, one more thing...I must ask you one thing (and warn everyone else  
that I will ask them the same question ;-) ):

You claim IDNA2008 is complicated. What do you include in that  
statement? When I have implemented IDNA2008, the problems has been in  
for example (if you look at the tables document) implementation of  
this rule:

2.2. Unstable (B)

      B: toNFKC(toCaseFold(toNFKC(cp))) != cp

*THAT* is not easy to implement, and very hard to get right (and  
understand).
