Do you care?  You are ID'd within the application layer.

Heck no.

Yes!  And, analagous to EUI-64 (where some portion of the upper 64 bits of the 
address are advertised by the router and the lower 64 bits are derived from the 
Ethernet MAC address) derive the lower 64 bits from the callsign.  This is 
EUI-64 stateless autoconfiguration (RFC2464, 
http://www.faqs.org/rfcs/rfc2464.html).  Similarly to use of EUI-64, one could 
statically configure the address with the callsign and enough bits left over for 
2^16 substation IDs vs. the 16 you get with AX.25 (can't say SSID in this 
context:-).  No more ARP or DHCP!  Adhoc v6 WLANs will just work with v6 addresses.
