What solution is there for a backup/failover pool for a multi-coin pool such as this? Cgminer explicitly states that mixing blockchains is a no-no, so setting a LTC pool (or similar) as backup won't work.
My intuition is that mixing blockchains is only a problem if you're using the --load-balance option. But I don't really know. If anyone has success with a backup pool, and knows for sure that it doesn't cause extra "detected new block" for the primary pool, let us know.
I've been using an LTC pool as a backup pool, and have had no issues (hashrate/payout are near what is expected), and it has switched back and forth several times.
