Smart Grids are one application: <a href="http://en.wikipedia.org/wiki/Smart_grid" target="_blank">http://en.wikipedia.org/wiki/Smart_grid</a><br>
<br>
In pleminary IETF discussions (an IETF groups has yet to be formed on
this), I've argued that the first thing to make mandatory is for a
Smart Grid to use IPv6. The demand for single IPv6 addresses for each
customer meter is too high to be sustained by IPv4 - it would exhaust
IPv4 address space.<br></div></blockquote><div>True, this is (or should be) a no brainer. Additionally with the should someone decided to give RFID chips an IP stack, IPv6 will be the only sustainable source of addresses.</div>
<div><br></div><div>I was more concerned about applications within the enterprise that give IPv6 and edge of IPv6. Knowing the pain most people go with VPNs and IF Microsoft's Direct Access (and a similar open source technology) can make that pain go away, I believe lots it might be such a killer application.</div>
<div><br></div><div>Do we have anything in the multimedia/VoIP arena that is better with v6 than with v4? </div></div><br>
