The only drawback is that their solution is and highly probably will be not for "general" public, they release it not outside of lab.....
I wouldn't necessarily assume that. Disney has a pretty strong history or releasing internal tools as open source.
http://www.disneyanimation.com/technology/opensourceThe big VFX & animation houses like Disney also play a pretty important role in driving feature development in commercial software like Mari & Nuke, even when those packages started out as in-house tools.
If this method proves useful in production I would not be surprised at all to see it pushed out to either third party commercial software or potentially even an open-source library.
Regardless, although I only skimmed through the paper it would seem that it contains all the detail needed for a third party developer to write their own version of the algorithm.
