[Sis-csi] IPv6?

[Edward Greenberg]

I think that I will just continue to be the Devil's Advocate.  Let's 
see how this logic plays in an area where someone is going to have to 
make a large investment.   I hear that the program is supposed to 
eventually get to the Mars.  At and on the way to Mars the standard 
DSN modulation techniques are optimal. So when we go to the Moon why 
not use the standard deep space modulation methodologies instead of 
requiring the stations to radiate TDRS modulations?
