One of the biggest problems with all of our

fact that Sun's own OpenSolaris distro does not allow

Things probably would look very different if Sun's
top management did not summarily ignore all of those
community distros. Instead,
they "had to" hire a Linux has-been to create
something that never received support from the
Solaris old hands.
I quite liked Ben Rockwood's take on IPS:

I can say that I used to hate IPS, but no more. It
isn't perfect, but when you accept it and learn to
work with it, it doesn't seem so bad.
Alasdair.
One of the most distinguishing advantages of IPS which is also one of the best
selling points of OpenSolaris, is that, after you do an image-update to a newer
version of OpenSolaris, your current version will be persevered as one of the
dual-boot options during a reboot. I know I have talked several Ubuntu users
to take a look at OpenSolaris exactly because of this ZFS-associated feature.
Nothing saddened me more than the fact that Stephen Hahn is no longer with the
OpenSolaris development team. However, as honorable as Stephen is, I am sure
he has laid a solid foundation for IPS to move on and form the basis of the
Solaris.next.
That has nothing to do with IPS. It is a ZFS feature. I implemented
exactly the same stuff on BeleniX using SVR4 packaging.
It does have something to do with pkg(5) in the sense that it is
integrated with functionality such as boot environments.
If it wasn't integrated, the user experience wouldn't be the same just
as you pointed out with Belenix's own integration.
However, one related thing to keep in mind is that the zone creation and
management mechanisms are now tightly integrated with the image
packaging system. Just as the automated installer is, etc.
Other distributions will have to re-implement a large amount of work if
they choose to use a different packaging system.
