We have used the National Instruments GPIB-Ethernet (10 Mbit version) 
with a driver based on the NI driver package and an older version of 
StreamDevice, all on vxWorks. This never really worked well, probably 
because of the glue code I wrote to interface the NI code with the 
StreamDevice layer. We recently replaced one such system with the 
combination of NI PCI GPIB/Linux-GPIB/StreamDevice/Asyn and I am much 
happier with it. We are running EPICS 13.14.8.2 on Scientific Linux 4.4. 
 I hope to never use the GPIB Ethernet boxes with EPICS again. If you 
require a small form factor, you might look at the above configuration 
hosted on PC104 hardware.
