I was running FogBugz on Linux at a particular start-up in either 2001 or 2002, so what you say isn't true. The original project must have been started much earlier than 2005. Edit: See reply below, must be getting old :-(
So Thistle, the transpiler, was written either summer 2003 or summer 2004 (it's not entirely clear if he employed the intern that summer or the next) and Wasabi came later (so 2005 is probably correct).
