Our normal testing efforts would be good at long-term traffic generation
(1+ days) using our tool which is somewhat similar to iperf.

We haven't bothered with roaming before, but might can work that in for
at least limited testing.  Maybe a laptop running hostapd strapped on a roomba
would be fun :)

When we can get the virtual station (and hopefully virtual APs) stuff
stable, we'll start doing some tests and try to figure out how to publish
it in a useful manner for others.

I was hoping someone had a post-receive trigger sending email to some list
that I could subscribe to.

Thanks,
