An early adopter of SMS reference

A while back, I mentioned that there's a product out that allows libraries to manage a reference service based on SMS (user sends question via text messaging on their phones, a librarian replies using their e-mail program, the software then transforms the e-mail to a text message sent back to the user's phone). From a recent posting on Dig_Ref, I've learned that Southeastern Louisiana University is going to launch such a service. I'd love to hear how it goes.
