frame is mixing two distinct issues. TortoiseSVN manipulates the
Windows systems configurations when installed and requires a reboot to
activate the ability to open a folder and get the varioius TortoiseSVN
browsing and display options. So installing a shared copy will *NOT*
provide all the TortoiseSVN options. TortoiseSVN also provides
credential management, to store SVN credentials encrypted locally.
Again, that's in the local sytem's configuration, and built into
TortoiseSVN.

So, while sharing a copy of the binary kind-of/sort-of/almost works,
it's as likely to be completely broken as sharing the same Subversion
binary from an NFS drive among multiple versions of Linux. Just Never
Do This(tm).

The separate issue is the shared CIFS drive. This can work great,
until it doesn't. There are *inevitable* delays between when one
person, modifying files, has published a write operation and someone
else with another access to the same shared drive cannot yet see the
change., Unless the authors of Subversion, and the structure of CIFS
shared drives have been very, very careful to handle atomic local
database operations, frame is in real danger of submitting
simultaneous writes and causing... well, chaos.

This can certainly work with light loads and only a few users, or
possibly with personnel who don't modify the same parts of the working
copy at the same time.
