don't be concerned that GUESS isn't being put to heavy use. LimeWire has still put support for it in the software, and may plan to use it for requeries... so if future versions decide to always use it, old versions will support it.

also, the fact that they're not using GUESS exclusively says alot. it means that despite being able to attribute it to themselves, they realize that there are other (better) ways of improving the network. in this instance, the better way is 'dynamic querying' ... see http://www.gnutellaforums.com/showth...5107#post65107 for a short overview of how it'll work.
