RE: shared checkout of large binary files?

Have you considered creating a read-only repository that is outside of
the svn repository that is updated using hooks after each commit? Your
users could create sym links to that. Or just access it as a share or
mount it somewhere on their local PC... making sure that the group/users
only have Read permissions.

Or, show your users how to export when they won't need to be doing
