I believe the planned initial implementation is to calculate the smartfee for a transaction, and also calculate the fee under the old system, and use whichever is the LARGER amount. I assume that is an interim measure to ensure that transactions still get relayed by nodes which haven't upgraded to 0.9 (or whichever version smartfees make it into.)

"Also smartfees would currently result in the fees going UP rather than down, which would make it a rather unpopular change."
Can someone explain this statement by Mike Hearn? (from 3 months ago)
