We're reaching out to a number of open source font developers so I bet they have been contacted. I'll inquire. I think the current priorities are international language fonts actually, but other beautiful fonts are still welcome.

Thanks for the insight; that clears up a lot.

http://typekit.com has some excellent fonts, I use Museo all day, but they just added Adobe

Agreed... the thing with League of Moveable Type is that the fonts are open-source, which is why they'd be perfect for Google's thing.
