Where is Btrfs and the unreleased Xserver 1.8, for testing?
I'm taking a shot in the dark here, but I would venture a guess that both are too bleeding edge to make it into SOHO 6. I think that even trying to "play" with either of those in a testing scenario would render a VL 6.x system useless - they probably depend on updated "everything-important".
I think it would be good for vector to release two SOHO versions at one time, the 32bit and the 64bit
for those serious SOHO users on newer machines.
Again, a ventured guess is that the amount of time put into the 32bit release has been so great that it's virtually impossible to release a 64bit at the same time, let alone anytime in the near future. Hopefully VL7 will be able to produce a viable 64bit release.
