Depends which link estimator you use. MintRoute's estimator adapts, but not that quickly (think ~8 beacon intervals, so a couple of minutes). MultihopLQI adapts a lot more quickly, but there's still a problem if the links change significantly between receiving an update and sending a packet. E.g., if A sends a update saying B->A is LQI 107, A moves 20 feet, changing the LQI to 80, then B sends a packet, it will think it has 107 when it only has 80. There's a pretty straightforward tradeoff between the cost of adaptation and the rate of adaptation.
