the reason the search architecture for the Acquisition beta is different than the currently released LimeWire is because LimeWire has not yet released a stable version with the new architecture. it is still undergoing heavy revision in the development process. Dave just happened to download the code at a time he thought it was stable.

Dave even says it .. " Search performance is a core-side issue (LimeWire), so while I appreciate any effort to inform me, it's directed at the wrong person." So yeah -- the essential functions of Acquisition are _exactly_ the same as those of LimeWire.
