yeah, that's where I'm still a little confused about pip and a "wheelhouse"
-- other than PyPi, is there a way to put a pile of wheels somewhere and
point pip to them -- i.e. simple http or ftp server or something? Or are
folks going to need to download the whole pile first, then point pip at a
local dir?

Temporarily you can put them on SourceForge or on any public download site.

Thanks -- I'll try to do that later today.
