Well - Posix has since deployed IPv6 on most of our core. I did post 
something on this already - and basically met a wall of silence.

I am finding that some routing devices (eg. Mikrotik) are unable to use 
IPv6 natively... which is costing me.
I recently purchased a NPE-2G for a 7600 - and hope that this will 
future-proof me for a while (to 'fix' the Mikrotik problem).

I'll be offering my Hosting clients and access customers with dedicated 
access (digital lines) IPv6 service soon - followed by service to my 
"directly accessed" (ie - they directly dial into me) dial-up customers.

I am peering and transit-ing with Native IPv6 already.

This needs to be answered.

My pet example - UniForum SA - who peers at JINX (there are 14 odd ISP's 
there - all very independent)  and uses two transit providers - will 
*not* be getting a sub-allocation from an LIR.

The PI debate: This either needs to be done before the next meeting - so 
it can be voted through - or there needs to be a resolution to allow the 
result of such a discussion held at the next AfriNIC to be accepted by 
the community kinda on the spot. We've delayed this long enough already.

Thinking out the top of my head...
Why do we all need to hold full routing tables? I'd expect to see a sort 
of DNS type model come up - so you look-up a route before using it... 
and then just have a very small number of cached routes in the table... 
throw away old routes as memory fills - etc.
Then again - there are only 700 odd IPv6 routes for now? (Growing - but 
slower than IPv4)
