Open Source Registry Projects?

[Bret Fausett]

The recent traffic on the list coupled with ICANN's forward progress on 
new gTLDs (a new RFP may go out later this year), has me curious about 
the various open source registry projects out there. I am obviously 
aware of the ISC project, on which this list is centered, and I'm also 
aware that the .NZ registry code is open sourced. Links below. Is anyone 
aware of other projects? Has anyone done a feature/stability/performance 
comparison?
