First of all thanks for setting up a second pool for everybody; I recently got into the BTC hype but was having trouble going at it alone. I've been running for about 8 hours with little to no problems, although I don't have much to compare to seeing this is the first pooled experience I have. The only issue I've seen so far is occasionally DiabloMiner will give the following feedback:

85413/90697 khash/secException in thread "DiabloMiner Executor (GeForce GTX 295

It would seem that the work returned is null and cannot be parsed. It corrects itself after a while, probably by asking for more work until something comes back. Forgive my noobidity if that's an incorrect assumption.
