One thing to consider is space, if you only have a couple of videos then it may not be a problem, If however you have lots then storing the files could be tricky.
Saying that if you had an external hard drive hooked up to one of the stations (I suppose even an old RM would do), shared it out then you could use it as sort if a media server type thing? As long as you had nothing else running on it I guess it could work?
Think about backups of the files to, you don?t want to go to all that bother just to find out that someone has accidentally deleted one of the videos.
