I suppose most Care2x clients will operate under MS-Win OS, so WDM will be the appropriate technology to use.
That suggests that you have few, or no, previous experience with hospital IT.
Care2x is open source and free. Micro$oft isn't neither free nor open source. Micro$oft does not like open source at all. An hospital that relies in Windows is arguably an unreliable and unsecure hospital. Contrary to what Micro$oft hardly tries to convince you Windows is unreliable and full of back doors. Security policy is unenforceable as Windows networks are fundamentally unsecure: anyone with boot access to a terminal may easily and instantaneously acquire administrator privileges.
For years hospitals have not relied in Windows neither for their main "heavy" software, nor for their (terminal) clients. In fact concepts like "secure" or "reliable" are difficult to conciliate with words derived from "Micro$oft".
Instead, I would expect that most Care2x installations would be made over something much more secure, something like BSD or Linux.
Those systems also have the added value of being both free and open source. Additionally, under Linux there is a beautiful way of making a hospital network that involves LTSP (The Linux Terminal Server project: http://www.ltsp.org/) and SSI clustering (openSSI:http://openssi.org/) and Heartbeat (http://linux-ha.org/heartbeat/). That way you will have clustering with high availability and transparent node registration and load balancing. Also you will have NO MASS STORAGE in the local terminal, meaning that each time that a terminal is leaved unattended or is disconnected there will be no information available to be carried out of that institution. How is that for clinical (or operational, or financial) data security? Also, looking at the hardware side, local terminals may be constructed from old, recycled, cheap hardware, starting from old pentium II 300 MHz to high tech over 3 GHz Opteron 64.
