Hey Ronny,
maybe it's good to also state your overall goal: running
tests in virtualenv-environments with different packages
pre-installed.

probably rather a hook for setting a single gateway
pytest_makegateway(txspec) -> execnet gateway
because management of multiple nodes and their setup
is its own concern - some nodes might not come up etc.
In the --tx specifciation one could say e.g.
popen//python=python2.5//virtualenv=docutils-0.5,mercurial-1.2
and a pytest_virtualenv plugin could take it, call virtualenv
and eventually start up a gateway with the venv/bin/python.

To get started, i would first try to get things working with
popen, then extend to handle remote places - would you want
to automatically install virtualenv there and/or require
setuptools, btw?

something like this could make sense. It's a second step, i'd think,
though.
Can you imagine working on a branch to try implement these hooks?
I am willing to help/review.

yes, working from concrete uses (a pytest_virtualenv
plugin) makes sense.
best,
