Tiger Tools

Not to start this one up again, but I need a little more ammo here.

My company is considering (the executives, not me) getting Tiger Tools.  I
used it on a sandbox, no apparent harm done, seemed to help on interactive a
bit, yatta yatta.  However - the IBM standpoint of "this is bad, don't use
this, we won't help you if you do" is a hinderance to my buy-in on TTools.
Here's a couple questions.

1.  Since the tool appears to work, will IBM release a PTF which will
disable it?
2.  What does it *actually* do?  Any nasty under-the-covers stuff, or is it
really simple, anyone with half a brain could do it sort of things?
3.  What will IBM say if you have a problem and they find you have TTools
installed?
4.  Is there a legal aspect to this that IBM could use against customers?

I firmly believe that IBM hardware/software is good.  Any workaround on that
generally decreases your reliability and availability, in my mind.
Pros/cons to TTools @ an executive level would be great.
