At the moment you have only ETX... you can set custom "link quality 
multipliers" to each link, but you won't get ETT.

Estimation of the link rate is a little bit difficult, especially because many 
links don't carry unicast traffic most times. At the moment we are looking for 
code which will read bandwith/signal strength and similar layer2 data from the 
OS.

If anyone knows the necessary API on WINDOWS to get signal strengt and 
bandwith for each adhoc link, please contact us.
