Well, [Brady] and I have been making great strides in NetMRG, which you can follow in the NetMRG CVS Tree. We're working for an 0.9 release - but we still have a number of showstoppers (see TODO).
We hope to have this done in a couple weeks, but no promises. It's currently in a functional state - but not in a releaseable state yet. I'm sure donations might speed up the cause ;).
