The Slac guys have played with it some - there is a recent paper here: http://www.epm.ornl.gov/~dunigan/netperf/bulk.html Our local slac data users haven't found it useful since I2 bandwidith is currently available - Lucy E.

Yes. Works just nicely between Cisco and Extreme Networks. Only bad thing is that the 3GE for the GSR only has max 2450 MTU. Highly disappointing. The PA-GE has 4470, the 1GE for GSR has 9180, the 3GE for the GSR has 2450. -- Mikael Abrahamsson email: swmike@swm.pp.se
We use it extensively, since all we do is VPNs, and path MTU discovery is broken in too many places. This allows us to carry unfragmented 1500 byte packets inside tunnels. It does mean you have to get all the 10 & 100 Mb ethernet paths out of the picture. FDDI, GigE, ATM, Frame, PPP p2t, token ring (gag #!@) are alternatives.

Why?
In case of tunneling it's nice not to have to resort to fragmentation.
