I just registered so I could ask a question about the recent increase in transaction fee, but I'm not allowed to ask in that forum, apparently!

Anyways - there's a big broohaha about Gavin raising the default minimum transaction fee - my question is can I set up a miner to only accept transactions for which the fee offered is less than the default? Say, the network asks for 0.0001 BTC, can I set up a miner that will do transaction for 0.000075? How would transactions find their way to me? And would my mined transactions find their way back into the blockchain?

Seems silly that one person (or group of people) should dictate for everyone what they're willing to do - I'd be more than happy to mine the transactions that fall under the price range that 99% of the miners are asking for, if there's a way to accomplish that?

Any thoughts, advise or guidance will be appreciated.

If your asking on a newbie forum how to make a Bitcoin exchange, give up now.
