However, I think that AC could "open up" their EMR a little to perhaps allow interested parties to commission or write "apps" that would enhance the the functions that AC provides in a basic form. I'm thinking of all the extensions that have been written for Firefox, for example.
This approach (the gradual exposure of a documented interface), is a (if not the) path to success. Some of the greatest developments of the last 10 years are the result of focused, integrate-able innovation. The release of address-able, integrated interfaces are key to the viral growth and success of Facebook, Twitter, and Google.
The added holistic benefit is that AC can remain focused on their core value, while enabling other innovators to add value for AC users.
disclosure - we are working on projects that might benefit from such an approach, but I still recommend that approach whether it impacts our business or not.
