Acceptable font licenses?

Acceptable font licenses?

I was thinking of using some free fonts to spice up my project, but it seems there's a bit of a shortage of quality fonts released under CC or GPL licenses :(

Can anyone advise whether using a font released under the SIL Open Font License (http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL) would be acceptable?
