I'm using Joerger model VDACM waveform generators which I think meet your
requirements: 8 channels, 16-bit, +/- 10 V, memory for 32K points per
channel, 100 KHz clock. If you need better then 10 usec step size, they
also make a 100 MHz board in 12-bit but I haven't used that one.

See: http://www.joergerinc.com/VME.htm

I wrote EPICS software for the VDACM (VxWorks only at this point).

Let me know if you need more information.
