Nikos, this is great news! When the Linked Data Security Working Group
launches (we're still a ways off from that), we'd love to include your
independent implementation as an example of an interoperable
implementation. There will be a test suite to run it against, but that
you've generated a working example, I expect that it won't be very
difficult to conform to the test suite. That work is at least a year or
so out, but just giving you a heads up that we'd like you to be involved
in that work in some capacity.
