None since Gemalto (which is being sued by SFOR for IP infringment) currently provides the DoD wide SIPRNET with the security of MFA/OOBA. Uncle Sam does not like dealing with thieves! Should Gemalto be proven to have infringed on SFOR patents, damages (perhaps treble) could be awarded. Also, if Gemalto chooses to settle, a license agreement with SFOR would be in order if Gemalto wants to keep that lucritative DoD contract IMHO.
