I don't think many sites offer it, at least for the low limits. My guess is that the reason is rake efficiency. It can get pretty predatory and weak players can lose a lot of money in a short amount of time.
Not that the sites care if anyone loses any money, but they do care a lot about rake efficiency. If a weak player is going to loose money, the poker sites want get a good chuck of it, preferably most of it.
In a HU cash game, the poker site simply has very low rake efficiently since the good players will win the fish's money quite quickly and the site won't be able to generate much rake.
