I'm sorry, Mark, but there's a ton of open-source CRM software written over the weekend and published in a matter of days.

As a matter of fact, if you'll go through the backlogs here at Hacker News you'll see a large number of "Game/Site/Tool/Language Written, Released in 3 days!" stories by members of this very community... in languages from C# to Lisp to Java to C and even ASM.
