Exporting guides in Photoshop

I was wondering, is it possible to export guides from one psd to another?

Well, I found this (http://www.forum4designers.com/archive3-2004-4-67002.html) which says you can't, but it's from 2004. Photoshop has gone through a version or two since then. :) I'm still looking... I think there's got to be a way to do it.
