Thanks a bunch, I'd love to see that document when it comes out. It's not too urgent for us, we're fine with running good ol' patched version of 3.3.1-ad13, but we do want to switch to AOLserver 4 as soon as it's possible. So please do finish up that document.
I'm pretty happy with the constellation we have now where we can start individual AOLserver instances and they live completely separate lives.
However they do tend to eat up a lot of memory each, so maybe the built-in AOLserver 4 solution is actually better?
I really don't know which is the best way to go, which is why I'm looking forward to that document, and seeking advice :)
