I agree.
In a semi pro/professional environment you would have an editing station,
consisting of a Mac G4 (or whatever) with a dedicated RAID array.
Giving high-speed access to 23 other clients is only really feasible with
a SAN arrangement - and this isn't feasible with a lab of 23 iMacs.
Copying the video clips locally is the best way to go I think.
