It appears that both Mac and PC TrueType versions of Erik Spiekermann’s FF Meta Book and FF Meta Bold are being freely delivered along with the official Second Life client. The fonts’ .ttf files can be copied and used without system restrictions.
This begs the question whether the font was intended for free distribution among currently 4,598,897 users* or if this was a major oversight. A single cut is currently priced at around 50€ (FontShop).

You’ll also find ProFontWindows 2.3 – the windows version of Andrew Welch’s ProFont.

Update 2007-05-27: I met Erik Spiekermann yesterday. I’ve written a (tiny) update on the matter in a review.
* note that the actual distribution is less, as some users have multiple accounts per client.
