They will aslo not receive the same color of light... The one going
through the glass will be a bit greener.  Color correction filters and
neutral density filters might be needed to match exposure and color.

However, this technique has been used with good results.  One application
is macro photography with continuously variable base that can be made as
small as needed.  100 mm macro lenses might be a good choice here.
Dr. Paul Milligan has made and used this system.  Others have used it for
architectural and underwater photography.  It is bulky and expensive but
still cheaper than a Macro Realist!
