Cool. Well, it's ordered, I'll see what I can do when it shows up. :)
Considering that the protocol doc is all of a page and a half, I don't think
it'll be too tough.

I was thinking of a load monitor: load average 0-1 == gradually brighter,
higher than that does load average in Hz. It'd be fun to watch it
getting more and more frantic during "build.sh". :)

I saw that thing and thought it would be cool to have a NetBSD driver for it;
I say "go for it".

Anyone interested in a driver for this gizmo? It's most interesting to Mac
users, because it can power up most USB macs, but it's a USB device with a
push button, a dial, and an LED you can set to pulse or glow at varying
intensity.

The company is fairly supportive; I wrote to ask about driver docs, and I got
driver docs, along with a copy of a Linux driver, within about three hours,
and not during the business day either.

Anyway, I will likely try to produce a driver for it; anyone interested, let
me know so I can have some motivation. :)

Yeah, and then you go into a feedback loop in which the load increases
because more cycles are being dedicated to pulsing the LED...

...or can you offload that to the powermate?

It appears to have hooks for "set pulsing speed".
