There have been folks having success with the MS4W 1.5.3 binaries and 
SDE 9.1.  You might catch me on IRC to hammer out specific issues, 
but I think the MS4W docs explain how to swap the dlls.  Only other 
issue should be making sure the SDE SDK binaries are on your PATH and 
if you're using IIS that the SDE dlls have the execute bits set for 
the internet user.  Use mapserv.exe -v on the command line to confirm 
that SDE support is enabled.

Implementing support to allow MapServer SDE to do queryByPoly should 
be pretty straightforward, but I haven't found time, funding, or need 
to implement it.  I don't know if Steve has found a need for it 
either (I think he uses the SDE stuff pretty regularly 
also).  Patches always welcomed ;)
