Please read previous postings on the ADAPSO key/keyring system.  Unlike
the UK dongles, the ADAPSO keyring system does NOT daisy chain - ONE
kering does all communications for MANY keys, therefore propogation
delays are minimal.

Serial numbers in CPUs will not be acceptable for many reasons, starting
with what to do if your machine dies up to and including what to do
if you want to take some software home for non-simultaneous use??
