I think an unintrusive, different colored, PM bubble would be neat.
Playerworlds like to put a variety of different things on their worlds, which can be in different places on your screen, so if it was made into some kind of pop up, or scroller, it might interfere with something setup on certain playerworlds.

Maybe one color for gold worlds, one for classic, and one for hosted (3 different colors)
and you can choose which PW's you want alerts to come from.
Just an idea.
