It's a very good article.
It was recently posted on the freetype newsgroup, and the responses to some 
of the Author's questions are equally interesting...
http://article.gmane.org/gmane.comp.fonts.freetype.user/2370

One thing I noticed while reading this stuff, is that there is room for 
further improvement in the FreeType Plus package. Currently, sub-pixel 
positioning, and non-integer kerning is only used with the HintingNone 
option. But, it is equally applicable for HintingLight, and gives good 
results. I'll make that change in future releases.

Not sure.
I think he claims that by using FreeType's auto-hinting, Apple's hinting 
patent is avoided (which is true).
He further claims that his OWN ideas on sub-pixel positioning could be 
arrived at by common-sense and that there is therefore nothing FURTHER to 
patent (which is also true).
But, he makes no comment on patents surrounding sub-pixel anti-aliasing 
a.k.a ClearType.

Cheers,
Andy
