Standardization On: Signing url-form-encoded messages

UPDATE: Please see http://self-issued.info/docs/draft-jones-json-web-token-06.html and the implementation here https://github.com/progrium/ruby-jwt for another method for JSON specific requests.

(if you run into this post and are about to use a different method that doesn't pose any particular benefit, use this one - post an alternative if there's a benefit!)

PROBLEM

When a third party is given the option of sending a url-form-encoded request containing a signature value, we need a method of signing all keys and values as well as a signature, without the inclusion of the signature itself in the hash.

The classification of contempts as direct and indirect is merely a semantic device for
differentiating contempts that can be adjudicated summarily from those that can be adjudicated
only after adequate notice and hearing. When a contempt occurs within the "immediate view and
presence of the court" the judge is fully informed of all facts necessary to adjudicate the guilt or
innocence of the alleged contemner. When, however, the court is not so informed of such facts,
notice and hearing are necessary to get them.... 

In stating that "The failure of an attorney, without valid excuse, to be present... constitutes...
a direct contempt"... the majority opinion itself implicitly concedes that petitioner's contempt, if

Given

1) A drone can carry a recharge load for another drone
2) A drone can fly 2*X distance before a recharge
3) A drone must leave point A, reach point B, and return to point A.

If distance AB < X then no recharge is required.
If distance AB == 2X then
   Drone 1 flies to <X
   Drone 2 flies to <X, charges Drone 1, returns to A
