auto-detect TTL baud-rate?

While communicating between two ATmegas over USART, I want to be able to have uC1 automatically detect the baud rate that uC0 is using to transmit. Is there some generally accepted method of doing this?

Transmit a sync byte, something like 10101010. Then just run the timer between two high bits and do the math.
