Do you run the BFL-Software? Did you consider using cgminer instead?
I don't know how well the BFL-Software works, but cgminer seems to distribute shares among pools very efficiently, so only few shares are lost, if the main pool is lagging or down.
This is a good question.... I have heard very good things about cgminer.
Also now that we are getting to business... did you have any plans of putting up a status page OgNasty so we can check on the farm status?
