1) There would either need to be two separate ports, one for SHA256 and one for scrypt, or people would need to keep two miners pointing at the same port (one would continually fail whenever the other was active, not sure yet what the implications of this are)
That's pretty bad for people who only have one miner. Still a waste of power on the user's side, having one miner do nothing. If it would be implemented, it should have the option to distinguish between the two algorithms. Personally, for me it's a bother to change my miner to a different algo.
2) I'd like to have us mine BTC when all of the other SHA256-based currencies are not >1 profitability. The only problem is, we don't have anywhere near the hashrate to even hope to find a BTC block, barring some miracle. So what was thinking was, when BTC is the most profitable coin, until we build up enough hashing power, we throw all our hashrate to a secondary pool (I'd contact the pool owner first to make sure this was OK with them). It probably wouldn't be btcguild, but another prominent BTC pool (maybe even a PPS pool) where people would be sure to get paid for their shares. Of course this presents a logistical issue because people would have to make sure to have the same worker id/password created on the secondary pool as well.
That sounds like way too much work. So far I haven't seen all coins go below 1 at the same time. TRC often dips right down but LTC and FRC haven't been so low. Yet.
People who mine TRC should be well aware that the difficulty has wild swings and is therefore at times very profitable but on occasions is more of a waste of electricity. I do like the idea of switching, if all the settings can be manually set. For instance if TRC goes below a certain profitability it would change to FRC and switch back once TRC is over a set profitability value.
Also, the "unconfirmed" in the table of "Your Stats" seems broken. After checking it for at least 2 blocks it still shows 0.0000. Confirmed stays the same too, but Estimate is fine.
Hope we get a FRC block soon, I'm sitting on several k shares that are losing more value every day. Not really gonna mine FRC until a block is found or the stats show. TRC is fine~
