some questions should be, how long will 2.4 be
used and does 2.6 satisfy those needs ...

basically many security enhancements work with
vserver, some need less, others need more manual

I have no problem in adding enhancements (as optional
patches) to the vserver patchsets, but it will be
required to test and document this stuff too, so if
you, and others, are willing to test this, I have no
problem with rediffing it ...
others did adaptations of grsec to vserver which might
be tested and/or in use ...

I don't see such an issue in the ACL stuff either, but
it will require some changes to vserver to work ..
(as I said, if there is demand _and_ folks doing the
testing, which _is_ a hard job, if it comes to things
like security, I'm willing to support those patches)
