Hi Ian;

This sounds like a good application
for the hand-held ViuScan from
Creaform, which I've been using
lately (and which I also
distribute). It produces meshes in
your choice of high, medium, and
low resolution, which are further
modified by the scanning volume, a
user-variable cubic area
surrounding the object at the time
of scanning (more volume=larger
triangles). The photo texture is
captured at the same time, but its
resolution is not determined by
that of the mesh. If you save the
results in *.obj format, you get 3
files: the mesh itself (obj), the
photo texture (bmp) and the
material (mtl). Let me know if
you'd like more details about any
of this.
