I do believe that the high-speed (more than 10% of core network speed) TCP
connection is almost exclusive to the research/academic community.

I think you're on the right track in the thoughts to develop a new TCP
implementation solely for the application you describe above, and that it
makes more economic sense to do this than to build with the quite a lot
more expensive equipment with larger buffers.

I guess the cost of developing a tweaked TCP protocol would be in the
neighbourhood of the cost of a couple of OC192 linecards for the GSR :/
