What's in a name - Ultrascale Visualization

The 5th Ultrascale visualization workshop at SC 2010 is focused on visualization at the exascale. What a great name - Ultrascale Visualization is always current - visualization of data at the largest scale and never requiring a name change. The key question: How do you deal with exascale computation when it is too expensive (in terms of time and power) to move the raw data off of the machine. Is in-situ visualization the way of the future?
