Carsten, this particular response is not helpful because:

1. You seem to be claiming to have knowledge about the proposed fix that
   makes it seem like the solution is a dead-end, yet you don't
   elaborate upon the claim.
2. You seem to be insinuating that there are deeper problems with the
   HTTP Signatures approach without expanding upon what those may be.
3. You make an appeal to authority (re: the "security experts" will be
   able to help.) without knowing who wrote the specifications,
   who is reading this thread and commenting elsewhere, nor who has
   already reviewed the specifications.

The reason we sent the initial message out was because we wanted
feedback from various communities, including the "security experts"
whoever those people may be. Responses like the one you make above don't
actually help us identify issues in the protocol or approach that are
being taken. I know that you probably did not mean to come across as
condescending or patronizing, but you have.

I'd like us to focus on technical issues and helping each other rather
than the sort of exchange above.
