Yes, they were demonstrating this at SIGGRAPH in Chicago.  I got some
literature from them, but its on loan right now, so I can't quote the
specifics.

I wasn't aware of such a limitation.  I'm not sure what you mean by
"scan lines", since the output of the scanner depends on how it moves
in 3-space.  Their literature describes two motion paths: linearly along
a motion table, or circularly around a model platform; the latter was
what they showed at SIGGRAPH.  I'm sure there is some range of
scanning resolution supported by the device, but how that corresponds
to physical space on your 3D source depends on geometry, etc.

Most of the other scanner technology that I've seen consists of 3D
point digitizers, usually based on ultrasound technology.  Some of
these vendors are "little guys" in the computer industry; one of them
at SIGGRAPH had never heard of SCSI!
