I may have missed it, but that was not what the docs said that I read. The
code is not stored on the HL. Only the private keys are stored on the HL.
The HL decrypts the secrets to return the text so it can decrypt the
assembly. Then the assembly can run as normal in memory.

Your .Net code running inside the little usb device? That would have some
scalability issues I would think.
