slapo-memberof nested group behavior

Dear all, i know that nested groups have been discussed in detail before- just wanted to know what the priority of implementing nested groups through slapo-memberof or otherwise is. The functionality already discussed is:

If A memberof B and C memberof A then C memberof B

Functionality required would be that the memberof attribute handles recursion correctly. The administrative importance of this functionality cannot be emphasized more upon.

I am willing to help out with the slapo-memberof module if the functionality can be built into the current overlay only. Pointers on how to accomplish this would be appreciated.
