Transport protocols and bulk file transfer

[Susan Evett <>]

Scott,

I'm hearing a talk or BoF for Summer Joint Techs... and, you KNOW the Call 
for Proposals is ending on Thursday. If you can think of a way to get a panel 
discussion on this -- even an all out argument would be interesting! -- you 
could submit an abstract at: 
http://events.internet2.edu/2012/jt-stanford/proposal.cfm

thanks,

susan
