Oops, I left one thing out from my previous comment, which you could 
see if you read between the lines. To avoid this, I say that we can 
make this measurement, right now, today, without further upgrade. We 
have the EMCal Rich trigger, which triggers on electrons, of course it 
starts counting pions at 4.5 GeV/c. If this counting rate is too large 
(I don't know the value off hand), then we can simply raise the 
threshold of the emcal. I apologize for two things: 1) that I left this 
important message out of the previous email--we can do it with no 
further upgrade!; 2) the second thing that I apologize for is that we 
can actually do the physics that we stated in 1992, without further 
upgrade.

I remember Tom Kirk's words to me at the opening session of the late 
SSC in Dallas, when all the many national businessmen spoke and praised 
the SSC. I asked Tom what are these guys interested in---the higgs? No, 
he said, the upgrade.
    It seems that we've all got that way now.
