Using Gold As Online Currency

JerkyBoy writes "Salon.com has an interesting story about using gold for online transactions. One company that provides the service (goldmoney.com) describes itself as "an online payment system that combines the world's oldest money, gold, with Internet technology to provide a safe, easy and inexpensive way for anyone to transact business 24 hours a day. Payments are made electronically using GoldGrams(TM), which are grams of gold that circulate world-wide through the Internet." I wonder if I can configure the MIME types on my Apache server to send golden email attachments?" Hehe - this is basically the same thing as people have been trying to do with creating new online currency.
