Authorization server protocol

connect to, it also blindly fires off a packet to the authorize server:

getKeyAuthorize <challenge> <cdkey>

#OLD
#OLD keyAthorize <challenge> <accept | deny>
#OLD
#OLD A client will be accepted if the cdkey is valid and it has not been used by any other IP
#OLD address in the last 15 minutes.


The server sends a:

getIpAuthorize <challenge> <ip>

The authorize server returns a:

ipAuthorize <challenge> <accept | deny | demo | unknown >

A client will be accepted if a valid cdkey was sent by that ip (only) in the last 15 minutes.
