Can I use Xsan or metasan to collaborate iMovie projects and events?

If we put all our iMovie eggs in one basket (external raid via Xserve, will Xsan or other San management let us share and collaborate on these iMovie files? I've noticed the sun iMovie opens it scans and lists all the available events and sometimes re-processes them (quick). What happens when two users are accessing the same library (not necessarily the same project/event) will the process cause file corruption? Any way to get around this? We waste a lot of time moving events from one workstation to another.
