My buddy just finished (pre 3.2) RAF boosting 2 sets of 2 toons on 2 new RAF'ed accounts. He was able to double-grant (from two separate boostees) levels to a warlock, who hit level 60 with under 5 minutes /played.
I'm certainly hoping this is how it works, because I've already granted 30 levels to a new druid (ding 31 in ~2 mins), and when I'm finished boosting my 2nd set of toons I'll be hoping to grant another 29 levels to the druid to make him 60.
I trust him when he says he dinged his lock to 60 all by RAF grantable levels.
PS grant your levels in Org/IF near the bank, you'll get at least a few people observing you and calling you a hax0r and a cheater for it
