I've tried to explain in my latest response to Gary Ruben. To the contrary, I
see *including* an LGPLed component in scipy as putting an unnecessary hurdle in
the way of scipy users. While the LGPL is lighter in its requirements than the
GPL, it's certainly not trivial to comply with as scipy's license currently is.
It is an unnecessary hurdle because there are really not many reasons why a new
package *must* be in scipy. Small, well-separated packages are, in fact,
preferred for technical reasons above and beyond the legal ones.
A scikits (scitools, sciwhatever) project will provide the benefits of the scipy
community for the smaller, individual projects.
