MS-DOS onto web interface

There's an MS-DOS program that we use at work. Very simple, the whole folder takes up maybe 30MB. It works fine, but the problem is that problem is that they upgraded to a Mac at the office and everyone has newer PCs running Windows 7. I can install DOSBox and use the program just fine but it's a pain in the ass and the boss wants something more 21st century. I read somewhere that it might be possible to get it going online. That would be excellent since we'd have access to it from anywhere and no need to install anywhere.

Does anyone know where I can read up on this? I have Googled it, but any variation I've tried doesn't bring up the info I'm looking for. Any and all help would be greatly appreciated.
