Ooo, Subversion less stable than SourceSafe? ... red rag ;-)

No, it is simply that by sharing a working copy you lose all
protection against over-writing each others work. When you take out a
lock on a file it becomes writable, but not just by you but by anyone.
So any sense of security you get by doing this is a false one. Also
you are trying to work on code which is being worked on by several
different people at once. In your case you probably get away with it,
but in most cases you just end up not knowing whether it is your own
change which caused a breakage or someone else's.

Of course it is entirely your own decision how you want to work. There
is nothing in Subversion/TSVN that stops working if you do that, but
it is a practice that is strongly discouraged because it is easy for
the developers to get something wrong and lose their own or someone
else's work. We are not about to add a new feature which would
encourage unsafe ways of working.

I guess it depends on the network and the size of the working copy. I
have also used a working copy on a network share (but for a different
reason - it was my personal working copy, not shared with other
developers) and it worked fine for me. I think this part of the
argument is irrelevant.
