Nope….no penalty.
I have worked in facilities from 2 to 10 stations. (both of which I had a hand in architecting)
One with a dedicated fibre attached SAN. One with a Fast Raid where the 2nd machine was drive letter mapped the same array via GigE.
My experience is that PPro doesn’t much care as long as it has the path to the file, and that the topology playing back the file has the overhead necessary for all users to see it.
Because there is no “owner” or Database in control….It might be wise to set media permissions to READ ONLY once material is brought online and meta tagged to prevent inadvertent deletion when more than one person is accessing a file for work.
So bottom line….Browsing and using the same media files…no worries…project collaboration…is doable…but some workflows work better than others….
for example…serial passing of projects work fine….one editor starts and does an offline. 2nd editor in another suite picks up the project and does an online….or in some way pushes a project along.
But merging of projects split amongst multiple editors has traditionally created project bloat in PPro. This may have changed recently though….as I understand that if a sequence from another project is imported through the Media Browser Panel may not suffer the traditional redundant media object build up that was the case previously.
maybe someone else can chime in?
