All these tools .. all this infrastructure .. just one application? We are already using the same infrastructure to develop two additional applications - one in a mental health outcomes measurement study, and another for a palliative care system.
There is nothing specific to health applications about the technology, though! Any system that requires one or more of the key features of the technology: fast response over a low-bandwidth, high-latency network; strong security; low licensing cost; low administration / support costs can benefit from this architecture.
