Hmm.. Do you have any examples of such ISPs? I’ve only seen them give out a /64 to the PPPoE / WAN interface and then also have a routable /56 or /48 which is almost always available using DHCPv6-PD. The /64 is only used for communication with the ISP (can also be a /126) while everything else if up to the router to manage.
Although I do get a /48 from my ISP there is nothing I can manage about the subnetting. The 16 bits between my prefix and my networks are assigned by my router using DHCPv6-PD and there is nothing I can do to set these bits. They are assigned to my networks sequentially.
I don't think it is feasible to use those bits with a special meaning.
I think it's better to leave the use of the first 64 bits of the IPv6 free to the network admin, so he can distribute the bits between the /48 he gets from his ISP (for example) and the /64 subnets as he sees fit.
Given that we would always have a callsign encoded in the last 64 bits, I don't see why anyone would want to encode information about the country in the first 64 bits, especially since you can use compound callsigns such as PA/EA4GPZ if you're operating abroad.
Perhaps it would be interesting to have the information about the Maidenhead locator or GPS coordinates of a subnet (where this makes sense). Someone could use this info to make a geographical map of the network. However, I think that this info should belong to an external database (whois maybe) and not be encoded in the IPv6's.
