It's called "Maria-sama ga Miteru" ("Mariamite" for short)

It has been completely dubbed into English for distribution in Southeast Asia on the satellite anime station ANIMAX. It starts in March.
As far as I know, it isn't liscenced (probably due to it's lesbian content and that it's about as interesting as watching ameobas race)
I won't tell you where you can get it, since it isn't mine to give out (it is still copyright, liscenced or not)... but if you're enterprising, I suspect it won't be too difficult in a search engine (as long as you have the right keywords).
