A bolt of lightning on Multicasting

When I learnt about TCP/IP, Multicasting was a bit of a footnote in the appendix. I can appreciate that for broadcast / streaming applications it could have its use but ... in my day-to-day stuff I didn't expect to see it used "in anger". Then today I was watching a customer rebuilding 26 machines in parallel from a central server - a classroom application - using multicast. Data transfer rate was an impressive ... one of those DUH - of COURSE moments.
