Tessitura working with Micros POS software?

I'd like our Tessitura  to "talk" to our concessionaire's point of sale system so that we could pre-sell beverages, etc  in the box office.  Our concessionaire uses a form of the Micros point of sale system.   Maybe the bar staff scans a barcode on a drink voucher or swipes a mag strip card for payment and it deducts money from the patron's Tessitura account.   I suspect it'll take some sort of middle ware to connect the two.  Anyone out there doing anything like this?
