some strong points there...

just 1 thing about the grsec/vserver combo: i do change stuff to make
linux-vserver and grsecurity work seamlesly together. It's just that i
don't have the time to re-engineer grsecurity, pax AND linux-vserver
completely to make a perfectly integrated combo patch. The reason why i
don't deem this necessary is that there is just a very small overlap in
the functionality they both implement.

Since they are not "doing" the same and don't interfere much (except some
atomic operations, "selectable kernel parameters" and so on...).

I just try to please you in such a way that you would be happy to have
this kind of patch in "your project" ;)
