BoE epics on each Naxx boss

Someone on the forums noticed what at first appeared to be an oversight: Rusted-Link Spiked Gauntlets, from Grand Widow Faerlina in Naxx-10, are tagged as BoE, not BoP as most boss drops are. As it turns out, this is intended. According to Blizzard poster Verimonde, each boss will have one BoE item on its loot table. This has a few obvious benefits, as Verimonde points out:

• More trickle-down items from raiding - non-raiders, be they alts, friends, or just random AH patrons, get access to a few raid items

• More excitement - even if nobody needs anything from the boss, there's still a chance to get a potentially lucrative BoE (and badges, of course)

• Another income source for raid guilds

Although it isn't mentioned specifically, I expect that this BoE philosophy will extend to all raid bosses in Wrath. I think it's a nice idea. Let's say the average 10-man boss has a 12-item loot table and drops 2 items from it plus badges. If one of these items is made BoE, there's roughly a 17% chance to get it, which sounds reasonable.

My question: what will raids' loot rules be for BoEs? My guild typically does open rolls for BoE items that aren't needed by anyone present, so that's probably what we'll do. But how will DKP guilds handle it? Will people who need it for their alts get precedence? Will they be auctioned off and the funds added to the guild bank, if nobody needs them? I guess it'll vary depending on the guild. But between these BoEs and Heirloom items buyable with badges, raiding is going to be a lot more interesting for those of us with many alts.
