Thanks Ben.

I'm still working on various issues with the hardware. Soon I'll be able
to easily test several boards in the same system at the same time. Once
I've proven that works, I'll start nagging :)

Is there a better subject line I should use to get attention, or should
I just start CC'ing people?

Sorry if I sounded negative in my post. It's just a little discouraging
when you don't get lots of feedback. I REALLY appreciate all of the work
you and everyone else is doing.

Ira
