Parallels Plesk Automation

[spaceout]

Has anyone tried out Parallels Plesk Automation? Apparently it allows you to easily separate mail, web, dns, database, etc to multiple servers and manage them all through one "management node".

One hang up I've found so far with the management node...

* PPA does not support kernels with the grsecurity components

...but I have yet to find out if this effects all of the service nodes as well. It's also Postfix only for the mail server.

This really looks exactly like what I've been looking for, but I would love to know how well it would work alongside ASL.
