Indeed, the whole reason many of us do any work on Sage is to help our
research projects. The principle of helping Sage to help our individual
mathematical pursuits is actually what makes it consistently stronger as a
system.

I'm trying to run Django inside of the Sage python and import the sage
libraries. (Idea: Hey, look, a web server that can find derivatives!)
The Django install into my Sage install went fine, but I'm getting an
error when trying to import the Sage libraries:

Cool, I'll give the patch a shot. It looks like some other projects have

Hm, the issue is that there's really big startup costs for Sage; it looks
based on my cursory understanding of subprocess that there's a couple
seconds of hang-time for each calculation one wants to execute. This
doesn't really scale. I know there's something involving spawning a pile
of
machine code from
within Sage, so you need to have a plan for how to isolate it from the web
frontend. Importing it all into one process is a bad idea.

Hm, wouldn't this just be a direct product of the individual group

according to an 'obvious' group action. Should we also expect 'obvious'
