The original version of Instant Commons had it right. The files were sent straight from the WMF to the client. That version still worked last I checked, but my understanding is that it was deprecated in favor of the bandwidth-wasting "store files in a caching middle-man".
If I were a site admin using InstantCommons, I would want to keep a copy of all the images used anyway, in case they were deleted on commons but I still wanted to use them on my wiki.
