I would rather not use JS, but sadly the title tag wont cut it.
FOr an idea of what I am using it for, see

I already use the title tag now.
The only problem I instinctually have with the above code is that I think it will conflict with vb's capture of mouseover events.
Still. It may get me a little further to my goal. A promise is a promise. PM me your paypal address.
If anyone has a smoother approach... I could still be willing to part with a little more cash - but not as much now (or ill go broke)!
