I would have loved this in 2008 for the Beijing Olympics. My team created the point of sale, which included printing specialized tickets on specialized printers. These were going to be deployed across 1,000+ Bank of China locations, including many in pretty remote regions. Instead, we created an applet to handle the IO with the printer. It was a nightmare. All sorts of little differences between Windows XP & JRE made it ridiculous hard to debug. While the banks were given exact specs, the culture was such that whenever they would have a problem, they insist the machine was the right spec, which wasn't true 90% of the time.
