I'd have to hitchhike down from the Yukon. But if I can get the time off work, I would be there with bells on! I would pay a course fee in cash, labour and/or bicycle repairs... whatever is most valuable to you.
(a) how many podcasts you've listened to
I'll be honest; not all of them. But I've bought Ianto's book, built a test RMH (waiting for better firebricks), and listened to about three pod-casts (I do most of my permies-surfing at work where I don't have access to audio

).
I've read almost every thread on Permies.com about RMH and studied the information Ernie and Erica have posted here and on thier webpage. I've studied Donkey's detailed information.
I am fundamentally in agreement with the core-values of permiculture and I'm willing to be corrected/re-educated/respectfully debated with.
(b) whether you would be willing to camp in a tent
I'll bring extra tents... I'll sleep wrapped in a tarp if I have to.
(c) what time frame works for you - 2-3 days, one week, 2-3 weekends (to allow for cob construction)
One continuous course works best for me, though; if it's back-to back weekends I would hang around, offer labour and check out Montana.
(d) if you would prefer learning how to build a portable rmh - more likely to be a 2-3 day event.
Portable, non-portable, whatever you can offer.
