Hmm, the error isn't quite what I said:

1>V:\Trunk\stable\src\Include\Tools/async.h(268): error C2664: 
'boost::unique_future<R>::unique_future(boost::unique_future<R> &)' : cannot convert 
parameter 1 from 'boost::unique_future<R>' to 'boost::unique_future<R> &'
1>          with
1>          [
1>              R=boost::optional<in_addr> &
1>          ]
1>          and
1>          [
1>              R=boost::optional<in_addr>
1>          ]
1>          and
1>          [
1>              R=boost::optional<in_addr> &
1>          ]

But my other test cases of using unique_future (with simple types) work OK.
