I understood that.  What I was hoping for was feedback on how our sparse
vectors could be made better based on comparison with your internal library.

I was also suggesting that in other areas, interface with Mahout might be
made very easy without forcing you to migrate your current vector package
very much.  That is a particular
interest since this is the first potential use case for a user masquerading
their vector package
as compatible with Mahout vectors.
