I don't know enough about the internals of uBlas to say; I use an array library I wrote myself and retrofitting that library took me a week or so, including testing. I imaging it could be done in a couple of months of concerted effort by a competent programmer.

Not that I know of. The issue has been raised before, but there didn't seem to be much interest in the uBlas community. I agree that it is an obvious synergy; it would also make uBlas more correct in general.

Happy to help. Good luck - if you do decide to extend uBlas, I imagine that the work would be well-received.
