I don't see the point of 65K MTUs....Well, with almost everybody using PPP0E in germany and at least halfof europe our mtu is somewhere arround 1480. Many routers are braindead(ICMP lobotomiced).When you hit somebody on an ip2ip link or IPv6 tunnel your mtu goes down to even smaller packets and things live ftp or ssh simply break. I haveseen many gamers on mtu = 1024 and smaller.
I advise people doing streaming to not use MTU's larger than ~1450 for these sorts of reasons.
