Hi Nigel,
since you are only concerned about a couple of sample units, I would not be 
 too worried about the tin-whisker problem. Probability of failure is still 
quite  low for a single unit, even if massively higher than with lead 
solder. If you  ordered 10,000 units that would be another issue :)
Even if the part stops to work, you can probably take a toothbrush etc and  
you might be able to brush off all the whiskers (unless the short was  
I tried re-working RoHs boards with lead solder, and this does not result  
in shiny solder joints either. It doesn't even seem to change the eutectic  
temperature of the joint much.
Would be very interested in any actual test results you get with your  
boards though.

If I  was to resolder all the joints on something like this, using good  
fashioned tin/lead solder, where would that leave  me?
