I think Dnet needs to release a coherent statement (if they haven't) about their current slate of contests, what they've got planned for the future, and what their philosophy is in regard to prioritizing things. As far as I know, nothing of this nature has really been addressed.
With CSC (and before that, DES), I understood--you do RC5, CSC comes on the scene for a short while (during which a lot of people do CSC), then it's over with and everything goes back to RC5. With the current state of affairs with OGR, that doesn't seem to be the case. It seems like they've got this OGR contest ready to go, and as soon as it's finished, more waiting in the wings (OGR-25, etc).
Initial bad client versions aside, RC5 appears to be taking a massive hit from OGR with OGR as the default contest. It seems to me that RC5 is no longer high priority for DNET--they would rather move on to other things but cannot just shut down RC5 because that would be such a huge embarrassment. So, instead, they take the huge number of clients that were installed with the intention of cracking RC5 but were not explicitly configured to turn off OGR, and switch them over, shelving RC5 for the indefinite future.
My basic point is... by introducing OGR and future "default priority" contests, DNET is going to string RC5 out much longer than it should have taken, and they're not being respectful of the huge base of committed RC5 crackers who would like to see this thing one day finished.
