Autoexplanation of acronyms??

[jumpjack]

Guys, these acronyms are REALLY getting me mad. I just discovered the list of the scummvm supported games and their acronyms... and now here they are new acronyms like AGI, FreeSCI and whatelse...

Do you know that "strange system" which highlights words in sites and forums (AdSense? How is it named??), and shows tips upon mouse passing over those words?
It would be cool if such a method could be used, rather than to bore users , to give quick info about know acronyms.
Is it possible?
