[rpd] Anycast allocations and current policy

[Adam Nelson]

Jérome,

Thanks for participating.  Keep in mind that LIRs and end users can still
apply through normal channels for IP space even if the purpose is Anycast.
The Anycast policies provide another channel to Anycast deployments that
might otherwise be difficult to get through the other channels - but those
existing channels are still available.

Cheers,
Adam
