This may be an edge case seen from a strict web perspective but I
consider the browser the ideal tool for enrolling keys, regardless
if the keys are only to be consumed by the browser or by other
applications ("apps").  The Google wallet is AFAIK self-contained
and including enrollment (which makes the key app-binding simple...),
but I believe the Wallet is more like a a "technology preview" so we
shouldn't bother too much about that at this stage :-)

Anyway, from a Mozilla perspective it would have a profound impact on
NSS and PSM that would have to go one level down in the OS to be
able to do perform secure app-binding.  This is what I'm will do in my
SKS/KeyGen2 project.  This is also necessary for trusted PIN input
which is about making it harder for "bad apps" misusing keys in
the background.
