I'm pretty sure you can bypass that, even, by having the specific  
virtualenv interperter you want to run your script in with the shebang  
set to the right interpreter:

#! /pathto/virtualenvs/python

and it will run entirely in the virtualenv.

Yes, it's hard-coded, but for this use-case, where you're making the  
server on which it's to run, anyway...

Right?
