Thanks Kelly for excellent notes. I added some details about the
boards and enclosures.

In a development that could be exciting but probably isn't, I ran into
Kal Spelletich this morning. If I understand him right (not always a
given) he has both an Emotiv headset and a spare set of OpenEEG
boards. He said he's not using them and would contribute them to the
cause. I think the Emotiv headset may be fairly useless without the
api/driver/software but we could at least investigate their electrode
setup. I'm still on the record as being Very Skeptical about them.
Anyway I'll be by his studio later this week and see what I can come
away with.

Kelly suggests another ping to the main NB list which I think is a
splendid idea.

Rachel, may we PayPal you some contributions for the electrode cap?
