My only question would be why?
When we already have DA running smoothly on your choice of RedHat or FreeBSD, why in the world should anyone waste time porting and then maintaining DA for another O/S. Without turning this into an O/S debate, I can't believe there's anything OpenBSD is going to do better over FreeBSD. Personally I'd rather see the DA team work on adding features and improving what we currently have, than waste time having to develop and test yet another O/S. I realise everyone has their preferences, but surely DA is about running hosting companies, and not about a bunch of little kids who run slackware on their 386dx at home and think it would be c00l to set up a hosting company running off their DSL connection? Then again, I have been wrong before...
Anyway, just my 5 cents on a feature de-quest.
Cheers...
