I'm told we were the first to run Virtuoso outside of Sony testing.  Our
experience was that recording pairs worked at times but not consistently.
We're doing a test of new software in early November and may have different
results.

I think Sony is incorporating NetOps School, replacing some other
screen-sharing capability.  Our results, with new Dell ~1.2GHz. Dimensions
with Gb NICs, and Gb switches, has been that screen-sharing video suffers or
plain doesn't work.  It could be that this is due to limiting physics of
even this fast of hardware, and/or not well enough developed or implemented
codecs and/or other software.  The only way I'm aware of broadcasting decent
size, decent fps video/audio, in the Sony world, is through a separate
hardware network (video), which of course is what many would like to avoid,
both due to cost and limited flexibility (i.e., you can't add any computer
to the 'classroom' -- it has to have the special hardware connected to
everyone else in the 'classroom').
