Vince Kuraitus and I have a blog post up at the Center for Connected Health, a division of Partners HealthCare. Titled, What Will Microsoft's HealthVault Mean to the Telehealth Community?, the post explores the role Health Vault's Connection Center software may play in the commoditization of remote monitoring solutions.

Today, telehealth applications are based on point to point
relationships:  home health agency to patient; disease management
company to patient; health system to patient.

Telehealth devices and their connectivity are similar. There is a
proprietary chain of key components for a remote patient monitoring
(RPM) solution:  1) the RPM device; 2) a gateway — which could be
mobile like the Biotronik Cardio Messenger
or static like a personal computer — to aggregate data from multiple
devices and move data to a server-based application; and 3) the server
application that stores and manages the data in accordance with the
application, e.g., glycemic control, medication compliance, etc.
