As much as I would love this, I simply dont think it will work. Why? Epic is simply too big and has too much of the market and they are too far behind. I use picnichealth.com to deal with this EMR mess and I love it!
The pricing seems incredibly high, am I understanding correctly that they want ~$300 up front then $33/month thereafter? That said, working in this industry, I know exactly how hard it is to do this right. In many ways this is what it costs to do the job, if not more, but I'm not sure I'd pay it. There's the tragedy of the whole EMR/patient data story: bloody expensive, who pays?
EDIT: I have also used this in conjunction with healthtap. EXTREMELY USEFUL! Doctors love it!
