Around 5 years ago we demonstrated a full medical record and the software running on a flash memory card. We did this for the DoD who was/is distributing flash memory cards to all their soldiers. This enables just as claimed here the ability to view a medical record with software directly on the card. In our case we used a JVM as the portability platform and included a JVM on the card to run the application. We would then provide a JVM on the card for each system that the card was attached to. This is identical to what happens with the emulator that enables the running of linux. The security is a problem as in both cases the database could be copied from the card by the host os. However, this could be encrypted so that copying the database would be of little value or at least make it hard to decrypt. I think this approach is pretty promising and it worked quite well for us 5 years ago, and I still have the code that works on any windows machine. In addition, similar to this case, it could connect securely to external servers if desired/necessary.
In any case, it makes a good platform for people wanting to demonstrate an application on a system without having to reboot into another operating system. As for performance, I found it worked quite well on my 1.4GHz Pentium M notebook. It could be that the performance others have seen may be hampered by the low bandwidth of the memory card or a USB 1.1 connection. The emulator doesn't seem to be a problem, for me at least.
