I don't understand your example.

Depending on what you want ofcourse, but currently we've no external user-verification possibility so this should be
handled somewhere and the engine doesn't look seem the right place to me.

User management is already there by gsec, so i don't understand the problem.

Server is still there but catches traffic only and redirects it to the y-valve.

I understand your point, but for some reason i don't feel comfortable with it.

Well vulcan needs to go alpha ASAP and we want a solution that doesn't take to much time/effort, but still fits in the
architecture and will be useable in future too.
