Thanks for the suggestions.  Sorry for the delay in replying.

It might be feasible to add sparse matrix and vector datatypes and a
sparse blas, without adding any specific solver algorithms (which is
what I'd like to avoid).

If this was added to GSL, would you want to use it in GLPK, or is it
just something you thought would be generally useful to users of GSL?
