The technicians didn't really give it a chance. No-one in Management really encouraged us to use it. The only one pushing it was the Caseband Rep who was there to show us how it worked. To be honest, Management didn't really care how we fixed the snags, as long as the ship was "Servicable" for launch in the morning!
Actually, our guys are pretty sharp, and don't generally throw parts at a snag unless nececessary. They can usually come up with "the fix" using their own knowledge, experience, and the crappy Bombardier TSM. Most experienced AME's are like this, and some have quite the ego to help them along!
I don't think it would have saved us any money. Partly that depends on what Casebank was going to charge us for the service.
Personally, I found Spotlight, and the theory behind it, very interesting. I never heard the real reason for it's disappearance, but if you like I can ask around at work next week and get back to you.
If you don't mind me asking, what is your involvement with this system?
