Okay, I got it now, thanks so much for pointing out that sample scene file.
All I had to do is set reflection to on in the sphere and I saw the
spotlight shining back from it.  Great thing.  Now I have gotten a cylinder
spotlight to actually show up too, the weird thing is there wasn't really
any obvious reason for the not-working and working ways.  It's almost
metamorphosing the more I try to use it.  Typical thing because of so many
possible media settings I guess.  I at first even thought it was all because
of the sample file having a 'media on' in the photon block.   Not so.  I
tried with and without and get the laser light reflected in the media.
Curious to say the least.  I'm going to post this test render I have to
p.b.i. in a few minutes so it will prove to others it can be done.

Bob
