Yes, it's now part of 2.63 - http://www.blender.org/development/release-logs/blender-263/
hmm...
i looked at the Bmesh feature and it doesnt seem similar to Bsurfaces, from the screenshots ive seen on the blender website & from the tutorial video i saw on the Bsurfaces websites
i'll just have to until i get home.
