I don't think we will get IPv6 on UMTS/Edge/CDMA soon. At the moment there 
seems to be no chip that supports IPv6 for them, and they would have to be re-
certified to support it.

So if we want to share the online connection, we have to use IPv4. This might 
be a reason to use AHCP, but only to handle the address allocation in a 
private IPv4 range, we have to use NAT anyways.

I'm not sure how/if AHCP handles the IPv6 prefix delegation for gateways at 
the moment.


The more important thing is that we need to think about a way to tune our 
protocols for both cases (wired/mobil) without the need of configuration for 
the user.
