Plucking OPAC holdings data for cell phones

I haven't been involved this quiet little project my library has been working on involving cell phones and our OPAC, but now that the chief librarian has decided to post a message about it on our library feed, I thought I'd share it here. Basically, a select group of students in this pilot project have been given accounts that allow them to check to see if any group study rooms or laptops are available. The data is plucked from our OPAC and then using technology from Rave Wireless it is sent to the users' phones. I don't know much about how this is all being done, but if anyone is interested in hearing more, leave me a comment here to let me know and I'll report back in a new posting.
