Yes.

Boost.Atomic is an implementation of the standard atomic operations that 
work in compilers without atomic support and older versions of the 
standard. Both should behave similarly and should be interoperable when 
"is_lock_free()" is true for both std::atomic<std::size-t> and 
boost::atomic<std::size_t>

Yes, it should.

When do you foresee boost.interprocess

I don't know, it's in my low-priority list since users can use 
Boost.Atomic or std::atomic and Interprocess' atomic operations are an 
implementation detail that users should not use.
