user153: Are there any online or open source (i.e., free, or at least cheap) accounting systems that do multi-currency so that I can record revenues and payments made using BTCs in the same system that I use for USDs?
If not, are there any suggestions for how best to do this?

user5727: Check out http://my-btc.info, a free page to monitor the portfolio of digital currencies with profit / loss calculation including BTC and many, many other alt-coins.
Diskussions about the tool at the bitcointalk forum: https://bitcointalk.org/index.php?topic=220238.0
Also, I must say that Dario (the webmaster) is a great guy. Unbelievable what has been implemented in the last two months and he is always open to new suggestions.
Thanks and Greetings
