Is it true that Software Management does not use LanCaches?
I believe this is correct.
Apparently any module built around the new endpoint fabric does not use lancache. (this includes new KAV/KAM, software management, liveconnect, cloud backup to name a few). the new endpoint fabric apparently has local peer-to-peer caching or something like that. It's not well documented however there are passing references to it 'here and there' if you read the forums and so on, have watched webinars etc it's mentioned
I get the vibe that lancache will eventually be retired in favor of the new model.
