Any examples of actual XKMS applications?

Hi folks,

The comm team asked me if we have any examples of real-use XKMS
applications out there. The only one I've so far is the EIEN
contributed by Rich and Yunhao and that was quoted in the Interoperability
report [1].

Do you have other ones to share? Even the ones saying "this is how
we're using it in my enterprise" are interesting.

Rich, do you think it would be possible to quote the EIEN one or it's
better to not make it so public?

Thanks!
