IMHO secure hardware is not something widely available as of today and
have its own probs of distribution and branding (pls correct if my
understanding is incorrect)
how about usage of crypto ( or may be pki) techniques along with
available device ID's. It shall act as strong authentication, though
it will also have problems like management across different
platforms, certificate lifecycle management. But it shall be useful
for banking/payment applications.
