To flesh this idea out:
At present the Doctor has the Mining Server ( this is a simplification, as I have not seen DrHaribo's rig ).
This server picks up all our logins, sends us work and payments, and also goes looking for blocks and the BTC tied to them ( so that there is work and BTC to send to us ). So it has 3 modules. Miner login ( with the nice GUI ), work and payment distribution, and block ( & BTC ) hunting.
I'm going to assume it's one rather beefy server for the sake of this example.
If the Doctor had a second server which carried all the log-ins, work distributions, payment distributions, and simply made us look like one big-ass miner ( 1450TH of Antminer S27000 ) that 2nd server could then latch onto the original mining server ( so we'd be mining Bitminter's server ), but it could also latch onto another pool should the need arise ( as it works like a big-ass miner unit ).
So the second server would have 3 modules. Miner login ( with the nice GUI ), work and payment distribution, and 'pool logon' ( like with your s1 at home ). And the pool logon, like an s1, could have 3 pools ready to go in it. The Doctor could even spread his bets across 3 pools without us Bitminter users knowing. We'd think we were mining Bitminter; but in reality we'd be on Bitminter, Eligius, & GHash too ( all at the same time ).
This will be more work for The Doc, sure; but...
Who would be willing to pay for some 'Bad Luck insurance'? I would. Would others? Another perk to help 'guarantee' income? Like the pre-payment perk?
I just don't think those who are throwing money at mining gear whilst not thinking about return live in the real world. If MtGox can fall then others can to. And if those miners fall Bitcoin is dead. It's in everyone's interest to keep this pool as alive as possible. No-one ( bar a rare few ) is wealthy enough to just take a pile of £50 notes and set them on fire. Mining does require plotting & scheming.
As an aside I've just checked Eligius. They have also slowed down over the past 2 weeks. If this is a general trend across all pools then Bitminter will DEFINITELY need to be able to respond.
Remember, an experienced miner spreads his kit across multiple pools to cover his backside. So that a streak of bad luck does not ruin him. It's a reasonable enough risk-management.
