	I think this is really something that is dependent on your equipment,  
etc..

	There are a number of routers/switches/whatnot that do the right  
thing.  There are some that don't.  On infrastructure where you  
control there's no reason you can't decide to use /31's.  I might even  
use them with clued peers, but I don't think they'd be wise to use on  
a customer connection.  Some various combinations of the "it-depends"  
apply here.  There are reasons to not use a /127 in IPv6-land so using  
a /126 or even a /64 depending on the platform(s) involved may be  
required.
