I threw out the name ARPACK there like I'm some kind of ARPACK expert, but
the truth is that all I know about it is what you just said -- it's what
Matlab uses for eigs, and I want an eigs replacement too.  :-)  My time
frame for actually needing it is not immediate either.  But I'm trying to
inch my way towards being able to make contributions like that.  Working my
way through the prerequisites like getting my own numpy and scipy to
compile, etc.
