IPV6 and public key encyrption

[David Findlay]

I was just wondering about all this stuff. 

1. Are you guys planning on getting IPv6 address ranges and using these so 
the addresses are fully routable allowing links via internet tunnels between 
different wireless nets?

2. Maybe a custom Data Link layer protocol that uses public key encryption to 
secure data transfer between nodes?

3. Is there a network forming in Brisbane area? And will it have access to a 
repeater at a very high location, like Mt Cootha or something like that?

Thanks, BTW I am not on the list, so please CC any replies to me.
