Google has just rolled out the Google Mini, a $3000 100k document-capacity search appliance. This is a huge price drop, and brings this technology within reach of pretty small organizations.
This could be very handy for an organization with a big collection of electronic documents that they want to be able to quickly and easily search.
I could also imagine this being very useful to a coalition. Imagine buying one of these suckers, setting up some tightly secured access to the coalition members’ file servers, and then letting folks search the combined results.
