	as far as i understand, nokia/ericsson are so active in IPv6 and
	mobile-ipv6 arena because they are trying to push the idea of all-IP
	cellphones.  of course it does not have to be 802.11-based, but
	i guess they would like to get rid of all the expensive PBXes,
	so as NTT Docomo.  of course i'm not speaking for them.

	what kind of device the next generation iPhone would be :-)
