Has anyone seen a percentage of traffic that is statistically significant for MTU's higher than 1500. Stats that I see pretty much show 99% of traffic below 1500.

Are there any other suggestions, other than ATM?

Gigabit ethernet sounds nice but the MTU of 1500 is really restricting that technology.
While there are certainly shortcomings to using GbE as a public exchange infrastructure, I fail to see how a 1500 byte MTU has anything to do with it. In every network I have ever seen, there have very, very rarely been any packets larger than 1500 bytes.
The only case that I can think of where that becomes important is in a MPLS exhange model where adding the label to large packets would cause fragmentation or broken TCP sessions for the PMTUD challenged.
