Are they at all open to compromise? Where I work we have a school for special needs kids and I had a problem with getting data from the individual school districts. So what I did was to write a short program myself that did what I needed and asked them if they'd agree to run it on their servers. There was some initial hesitation but after I bought them lunch and used the opportunity to walk them through the code line by line they were willing to install it. I'd imagine a similar system could work for you. It's a public database so you could write something that ran on a client machine (so it doesn't compromise their security) and since it's internal it wouldn't eat into their bandwidth (which is the only realistic problem I could see your program causing, one query every 15 minutes is not going to take that much processor power). Have it send you short text messages when there's a change and you're set.
