Beware, Fedora is always fairly broken at first. An Ubuntu LTS and a Fedora release are worlds apart when it comes to general usability/stability.
I run both (stable and betas) and Fedora has way more bugs and regressions (right now, suspend is broken again in F17 and scala does not work because F17 ships with JDK 1.7 and the scala version somehow exspects 1.6. Obvious stuff like that are not likely to happen in Ubuntu because most of the software first goes through Debians rigorous testing.)
So expect to pay a fairly high price for this feature, but if you really need it go ahead.
