I think you mean real-life scenarios. Real time is a type of system used in industry as a control system. Some of those systems run the linux realtime kernel.

But I think this is what you want: http://www.cs.du.edu/~ramki/courses/...ics/notes/SUID

Do you mean real world or realtime (literally) ?
For the former, it's mostly used for shared dirs & sometimes group-priv access to executables. There are 100s of write-ups/examples on google.

If you mean real-life scenarios, then there are a lot of ways it can be used for shared folders. This is due to some shortcomings in the EXT file systems. Here is one example scenario:

If you use other file systems SGID may not be necessary.
