Lots of things would be nice.
The real question is how many people would buy DirectAdmin if it were available on Trustix Linux who don't buy it now, because it's not.
It takes a lot of commitment and a lot of resources to port DirectAdmin to a new platform, becuse then it has to be supported on that platform forever.
As for me, I'd rather see it supported well on the platforms it's already on.
Of course if you have a large enough purchase pending, then perhaps DA sales would be willing to consider it.
