Medsphere does own one of the front-end applications that RPMS sites use. There are a number of others, including a scheduling application.
Traditionally this group has been more focused on VistA. Only recently, in my experience, has this group been more open to the idea of the looking at RPMS.
Finally, I would suggest that any time one evaluates a project, they look at the availability of all the software. Does the project have a web or FTP site where software can be downloaded? (a la, the VA FOIA FTP site). Is documentation available?
