One of my colleagues dropped out of his undergraduate degree and went back to do his Masters in his 40s. Given his experience as an operating systems architect in the meantime it's not surprising he was accepted without a bachelor's degree.

For posterity's sake, do you mind telling us which university it was? Or at least what "tier" university it was?

In my experience I've found (ironically), that it's generally the more reputable universities that are actually willing to do this, because "celebrity" (and I use that word very loosely) professors can talk a promising graduate student in over admissions department's veto at those institutions.
