        The server should store all paths in a case-sensitive manner.
All clients (regardless of the platform) should be aware of concerns on
other platforms and warn the user when necessary at commit time or
checkout time. To override these warnings/errors, one could add a
properties to the repository (on the server) which indicate if it is ok
to disable some of the warnings. That is, if I commit two files "AB"
and "ab" into a normal repository into the same directory, the client
should warn me this might cause problems on case-insensitive platforms.
If I then try checking out file "ab" under win32 but the server
contains both "ab" and "AB" it should give me a warning about the other
varient's existance. If under win32, I try checking out "aB" but both
"ab" and "AB" exist, it should fail with an ERROR stating such a
varient does not exist, but "ab" and "AB" do. If there is only one
varient on checkout, the win32 client should be smart enough to realize
that casing does not matter (but it should retain the server filename
casing on checkout).

        Now, if the server has the property:
"all-clients-case-sensitive" set to true, then unix commits of the two
different files that differ only by filename casing will not display a
warning. If "all-clients-case-insensitive" is set to true, the unix
commits will get an error.

        This covers all major cases off the top of my head. What do you
