It's a poor play on words. Just to explain, import hooks were formalized in
a PEP:


Before then (in Python 2.2), it was possible but not quite so straightforward
to change import behaviour.

That's true, even if the directory is specified by a URL referencing a
remote resource via HTTP. Ian's module focuses on this core feature; my
module is somewhat more contrived (a hack), and involves extracting Python
code from XHTML. For me, the ability to remote import .py files was a bonus.

Sometimes, when exploring an API or working through a problem, it's good
to be able to go back and see what worked and what didn't. I suppose it's
related to the old-style SAVE command, but not quite the same.

I'm a relative newcomer to the language - I started learning it back in
the 1.5.2 days. I know some people here have been using it for much longer...
