# GREMLIN: the GRASP daemon       
#                                                                            
# This module is for use in a node that can relay GRASP
# but is not running any ASA. This version needs no initial
# dialogue with the user.
#                                                     
# Because it's demonstration code written in an       
# interpreted language, performance is slow.          
#                                                     
# SECURITY WARNINGS:                                  
#  - assumes ACP up on all interfaces (or none)       
#  - assumes BUT DOES NOT CHECK that layer 2 is secured           
#  - does not watch for interface up/down changes
#    (but does handle IPv6 address changes)
#  - use of QUADS security is highly recommended
#                                                     
# LIMITATIONS:                                        
#  - only coded for IPv6, any IPv4 is accidental
#  - survival of address changes and CPU sleep/wakeup is patchy          
#  - workarounds for defects in Python socket module and
#    Windows socket peculiarities. Not tested on Android.
