Hmmm... GNU libidn already seems to be trying to use machine-readable 
tables. I had a look at the GNU libidn page:

http://www.gnu.org/software/libidn/

It has a copy of an expired Internet Draft by Paul Hoffman:

http://josefsson.org/cgi-bin/rfcmarkup?url=http://josefsson.org/cgi-bin/viewcvs.cgi/*checkout*/libidn/doc/specifications/draft-hoffman-idn-reg-02.txt

This draft seems to be talking about bundling and blocking, which your 
draft talks about too. What happened here? Did Paul decide to let his 
expire?

Anyway, my only reason for trying to get machine-readable tables was to 
figure out which Unicode character categories were being used. Another 
way to get this info is to simply ask the registries. Or, we can suggest 
a list of categories and see if they would be happy with a nameprep-bis 
that limits the characters to those categories.
