I would be glad to see the final report of the senior project (and may be - before that - the collected list of publications you get just now).
I wrote once a little about the topic but did not know most of above references (other than Hayek) and elaborated soemwhat on alternate money at the time of hyperinflation in the 1920ies+ in Germany and Austrai. However, this is in German and highly inadequate.
