this (time taken to branch is hours).  I've seen plenty examples given about the physical
size or number of commits supported in an SVN repository, but nothing about the number of
branches and tags that can be supported.

Subversion branches and tags are just specially-named copies (you
don't even have to call them "branch" or "tag" if you don't want).
Copies in Subversion are cheap - each will take maybe 1KB of space.

You shouldn't have the same trouble in SVN as you've had in CVS.
