Unfortunately not, no.
The reason is the new encryption for the in-memory auth cache.
But that's not the whole reason: Microsoft issued a security patch for
the C-runtime back in April which also makes all apps linking to it
(i.e., basically all apps compiled with VS2008 and later) break on Win2k
due to a missing function in a dll. So even if we would dynamically load
that CryptBinaryToString API and not use it on Win2k, TSVN still
wouldn't work there due to this patch from Microsoft.

The patch from MS is here:
http://support.microsoft.com/kb/2467174
and since it's marked as a security fix, it's automatically installed
with Windows update. The function that's not available on Win2k but used
in that security patch is FindActCtxSectionStringA.

So sorry, but we just can't support Win2k anymore, even on the 1.6.x line :(
