There has been quite some interest in this in the last couple of months, so I'm sure it will get some momentum. The question is whether Jake and Olivier's points about the inappropriateness of the data structures can actually get a workaround or if this is (more or less) pointless.
If crfsuite cannot be cast into a scikit-learn style API, then I think pyCRFsuite should remain as an external package, possibly with convenience functions for converting between numpy arrays and crfsuite files. I feel it would be ugly to do such conversions behind the scenes just for the sake of including CRFs in scikit-learn. However, if you conceive of a possible solution, that changes the whole problem.
