Technically they're not =/

Every class's tex file was auto-generated, but is a series of 
[\XeTeXinterchar \'... \RelevantBlockClass] commands. I couldn't quite 
figure out how to easily go from integers to hexacdecimal, so that I 
could generate them in xetex by using \char"XXXX, plus of course this 
approach wouldn't allow autogeneration of any glyphs from the unicode 
blocks above FFFF, which actually covers a decent number of blocks.

Good point, done and done.

And if you know of a way to make TeX perform the equivalent of a 
dec2utf8(integer) function, I'll be more than happy to replace the 
individual glyph commands with some automated loopage =)

One more thing I think I'll try to add before putting on CTAN is an 
options list that lets you pick which unicode blocks to use, if you know 
which you'll be using, so that only the relevant ones are loaded.
