Why not modify Boost.uBlas so that it uses vectorization, then use 
Boost.uBlas as a basis to write other vectorization-aware libraries?

Introducing a new library that does it then rewriting Boost.uBlas in 
terms of that library seems to be more work; especially since both 
libraries would have a very similar interface.

I have used the GCC vector intrinsics, yes.
I didn't find it that hard. At least much easier than writing inline 
assembly.

Reading that sentence, however, I'm not too sure we're talking about the 
same thing.
Are you saying those intrinsics aren't enough to generate optimal code?
