What about shell-command-on-region? And the shell command is 'sort -u'.

You can find a port of GNU sort on the GnuWin32 site.

M-x sort-lines to get the same results.

If you only want to sort part of the buffer, just highlight the region
you want sorted and execute the same function.

I use this quite frequently!

Oops! sort-lines doesn't uniquify...

Cygwin has a sort function that handles the -u switch, but it means
installing the entire cygwin environment.

On MS-Windows, you can easily install cygwin and use the full featured
sort from cygwin.  http://www.cygwin.com/
