No efforts yet. I had, however, a previous small algebra template library and
did some integration with an external BLAS library using template specialization.
This idea still seems attractive to me, although my library was way simpler than

The idea would be to have uBLAS code instantiated as usual, but when particular headers
were included, some functions would have a specialization that would call the
external BLAS library.
This approach would also allow for several different BLAS libraries, and easily
switching between them.
