A service in a pool (where for sure some blocks will be mined) were you can pay a fee and tell them your txId and make them include automatically in next block. If they implement it would be an extra BTC earnings for the pool operators.

There are talks about changing the bitcoin protocol to allow adding fees to sent txs, or child-pay-for-parent type systems. We are not there yet, so for now, we need to place enough fees into txs before we send them. It's not difficult to get used to

Bitcoin Core 0.12 will support Opt-in RBF so that if you opted in then you can increase the fee by resending the transaction. Opting in involves having a different sequence number in the output.
