Any multi-currency accounting ledger that lets me use BTC? 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?
Just found Kashoo.  Freemium, or $10/month.  Haven't used it yet though.
