Our realtime system is using distributed data gathering via a bitbus
network.  Has anyone used bitbus in their control systems?  First,
does anyone have a driver for a VME chassis under PSos and/or
VxWorks?  Or any other kernel?
For you philosophers out there, how can I deal with the time skew in
sampling multiple remote nodes?  Is there a "broadcast" message that will
tell all ndes to sample thier data *now* so I can get the values later
by sequentially polling the nodes?
Any help will be greatly appreciated.
(excuse the spelling--good thing my quals were oral)
