Hi Vincent,

Thanks for the explanation.  That makes things clearer.  I guess
that's yet another reason for me to hate software patents :)

I actually think that continuing with the NSS implementation may be
the better course of action.  It means that the same well-tested
implementation (and one that has been FIPS certified) is being used
rather than adding yet another.  Fedora actually have an effort to
make all their packages use NSS
(http://fedoraproject.org/wiki/FedoraCryptoConsolidation) so this fits
in well with that.

The problem is more the fact that it's an additional copy rather than
using the system installation, which means it has to be patched for
bugs and security fixes separately.  For IcedTea, I'll look at
providing and using the option of using the system NSS and will also
submit this for review here if there is interest in providing such an
option.
