svn:external local file link

I've have searched the mailing list without finding anything related to
my question so forgive me if I'm repeating an often requestion feature.
 
Is there a way (or any plan) to have an svn:external link to a
non-repository? E.g, svn:external
file://networkshare//bighonkindirectory.
 
I need the ability to link in a network share (networked directory
tree). This directory tree is an existing code library that will not be
changing. I could add it to its own repository, but it is used by other
non Subversion projects and I'd prefer not to duplicate it. Is there a
way to do this? This is a Windows environment so svn:special isn't an
option.
