Friend of nippleworks, Ross-i-tron, just finished his Surly Cross Check touring / Colorado winter commuter. Hell, given how it rains many afternoons there, the full fenders make it a good year round commuter. Gonna put studs on that thing? I've asked him what's up with the rack stays that go down to his canti brake bosses, since it looks like he has seat stay rack bosses. I'll post his explanation when I get it.
Update: according to Rossitron, the rack is an Old Man Mountain model that was originally meant for his mountain bike (which didn't have seat stay bosses) and it got a new lease on life as part of the Surly.
