Looks fun reminds me of Google Desktop search from way back in the day - you know back in the days of google also selling a search appliance for enterprise data centers.
Although a good idea in principle, I found it cumbersome to configure and it only (at the time) supported ftp and http based resources - if your company made heavy use of Windows file shares you couldn't index them without also serving them over ftp or http.
I believe later versions improved on that though, but by then it was a dead product, and Google discontinued it.
