We use 1 svn:external per project that points to an shared directory in my
companies repository.
I find it a constant source of trouble. People forget that they must branch
the external separately and make erroneous checkins. When they branch the
external it generally is branched with a different name than the other
branch as it must account for the name of the projec that is branching it.
Our server address is different for remote access and on site access. The
external must be updated locally to point to the external address and if it
gets checked in accidently it breaks things. It may just be my client
(TortoiseSVN) but if I show log on the folder with the external its contents
are considered changes to an unrelated path and hidden when that option is

Perhaps others have had better experiences. When I read the svn book and
found out about externals I reorginized are whole companies repository to
make heavy use of them. Soon we realized the maintenence headache they
bring and we changed it again. Now if I could just get rid of that last svn
external my life would be much easier.

As an aside if it doesn't exist yet an empty directory should be added in a
readily accessible location that can be svn switched into. It helps useable
a lot at our company.
