No change in that path. But some "power users" wanted their IPv4-only applications like Skype to work so they coded a NAT46 work-around for the N900. It is clever, it works. Their process of feeling the pain of a very few pesky IPv4-only apps and working around it is all documented here: http://talk.maemo.org/showthread.php?t=60320 Running NAT46 code here: http://code.google.com/p/n900ipv6/wiki/Nat64D In the end (as well as IPv6-only near term in mobile), IP version agnostic apps will prove to be more reliable and therefore will get more market share.
