Well, having a v6 core will prevent from you running MPLS,

Suffice it to say that some vendors are already implementing

Any cell phone that uses data service to download a ringtone, wallpaper,
picature, use their TV/radio webcast service, or their walkie talkie feature

In addition to that Verizon wireless sells their EVDO aircards for laptops.

Dear list,
Since IPv4 exhaustion is an increasingly serious and timely topic
lately, I would like to point out something that interests me, and maybe
everyone else who will be spending a lot on Tylenol and booze when we
really do run out of v4 IPs.
