Yes, SVN was not really developed for file management, only version control.

Developers when given rsync tend to over use it, and actually suck up all
available resources running it at peak hours. or accidently sync the old
stuff over the new.
Scripted Tar, scp using keys, even kicked off from a usermin, or web control
button (suid), (or via CRON - after a complete backup) seems to work well
for many developers doing releases twice or more a week.
The issues with file permissions in any developer environment are best
handled via CRON file fix: chmod -R go-w /var/www/html | chown -r www
/var/www/* (which is a good security fix also).  Adding the developers to
the same group that the web server runs under in development should also
resolve access issues.
Of course adding webdav to the development platform for SVN writes to web
layer is usable (tortoise SVN right click) but all releases into a
production system must include a Content Management Changelist, Versioning
so a production SVN matches the DEV environment.  This requirement is
somewhat contradictory, as content control and webdav are mutually
exclusive.
Checking in and out via SVN from Dev to Prod using a SVN server (see tracd)
seems to work for many?  However it's universally suggested to check out the
new tree, then copy over the source to prod.  Leaving the .svn files in prod
is messy; even if you can exclude serving them.   Therefore a scripted scp
or rsync, svn checkout and checkin with complete backup is required, either
kicked off via web based RELEASE button, or via scheduled CRON is indicated
to insure that everything is done, and changes available for rollback.  A
rollback process should also be scripted (trust me, script your required
actions now, or deal with chaos later [don't tell anyone, but you can script
your entire job] - python is an excellent scripting language for such and I
believe DJANGO includes a good deal of SVN release tools:

For those running multiple web servers with redundant content (in high hit
TomCat servers for instance); rsync during low web hit window is still the
best production solution.  Of course a fiber channel based NAS or ganeti
server engineered for shared content is the s-hexy solution to be sure.
