Well, sorted by volume we are still coin 33 from the bottom, and I don't think he will delist 33 coins at once. But you are right we need to keep up the buying pressure. I got ~125PMC with 1mhs with little less than 4 days of hashing in total. If everyone puts some hashes to the pool, there will be sufficient buying pressure.
We could also groupbuy one of those new 60mhs or 75mhs miners, and point them to the hashcows pool

I probably average about 400khs and have got between 15-17 PMCs a day so far..so that seems to roughly fit with your stats.
