I was able to implement "Sets" via the oai interface via the following changes to the functions.inc.php file in the ocs/oai/include directory. Standard disclaimer.. Use at your own risk. This was only tested in a multiple conference configuration. It should work in a single conference setup as well.
BTW this is for version OCS 1.1.5.
This was the output of 'diff -c functions.inc.php functions.inc.php.orig'.
