Topic: checkbook app

I just moved over from OSX to using Linux full time.  Serves me right for using proprietary software that's not cross platform (i.e. Quicken) but now I have no way to track my expenses.  I saw that the Rails Rumble '07 had an entry for a checkbook app which looks perfect for me.  Does anyone know if that can be downloaded anywhere?  I know it's available for use on http://electriccheckbook.com/ but I'd rather not keep my financials on somebody else's server.

Else is there source code for another rails-based checkbook app out there?  I suppose I could roll my own without too much difficulty but I'd rather not reinvent the wheel.
