one of the problems is that most of the token solutions are still
institutional centric ... it only provides a single solution for a
single password.

We spent quite a bit of research on what it would take to have a
person-centric solution ... where a common mechanism would be acceptable
by all institutions (including meeting the highest gov. security
requirements). Purpose of unique "shared secret" for every institution
is countermeasure to cross-institution attacks ... so it couldn't be
shared secret based, couldn't be static data, and couldn't be subject to
replay attacks.

There were a couple problems 1) no institional organizations supporting
single person-centric solution 2) token vendors with business plans that
still has every institution providing their own institutional token to
every individual (looking at product of N-institutions times
M-individuals ... instead of an individual with hundreds of passwords,
they have hundreds of tokens).
