Thanks for all the thoughts and solutions to stone adhesives and
anchoring - pro and cons.  Ultimately I believe the cameras, wirong,
detection devices, etc. will be installed using the most approppriate
method for each device depending on location and material.  Wire mold
does not require the same degree anchorage as a camera.  The designer
does have an approciation fo the capitol and hopefully the detailing
will bear this out and the contractor will have the same level of
sensitivity.
