desktop search

I’ve had Copernic installed on my WinXP machine at work for a month or so now, and I absolutely love it. It makes it super easy to find a document, spreadsheet, or PDF report in seconds. I even let it slip out to a co-worker or two that I could search so easily and I’ve been approached sense then to help them track down a roque report. I want to explore the option of pushing something like this on to everyone’s desktop here, but I’ve yet to come up with any viable solution. I don’t want 10+ computers indexing the same content – that just creates too much hard drive thrashing and network traffic when indexing a file server. I’d like to have one PC do the indexing and the others share that index. Security is obviously a concern also – I don’t want users who don’t have access to “Folder X” or “File Z” to be able to search and come up with excerpts from those restricted areas. I have a feeling that no desktop search would fare so well. But anyway, that’s just some random techno-babble for you.
