Hi Hugh,
        I have the following suggestions for your survey.

1) Product Mix- include controlled impedance boards

2) Design Capabilities - include what file formats are accepted for PWB
Data (What version of Gerber, drill files, etc.).

 From a survey design point of view, I would also explicitly list several
design and manufacturing software tools in the hope of eliciting better
responses, i.e. (I hope I can name names on Technet- if not, please flame
me offline.  Also note, this is just an example list, there may be
others!)

ACCEL Technologies
AutoCAD
Best Proto
Cadence
CADint PCB
Data I/O (Synario)
HP RF Board Designer
Intergraph
McCAD
Mentor Graphics
MicroSim
OrCAD
PADS Software
Protel
Ultiboard
VeriBest
Viewlogic
Visionics (EE Designer)
Xynetics
Zuken-Redak

3) Special Technologies - include plugged vias.

Hope it helps,
        Cheers,
                Andy
