I've been using the Promixis software since freeware girder. Global Cache is fantastic hardware for that software. The Promixis software and Global Cache hardware is a fantastic one two punch!
Then there is Cinemar, Charmed Quark and Homeseer.
For the money though the Promixis and Housebot software is hard to beat!
Housebot! I bought that years ago. I thought it went south when Meedio did.
I've also bought Cinemar, and tested Charmed and Quark. They needed to mature back then. Maybe it's time to revisit some of them. GLobal Cache is already on the list for the rack.
