sorry..i'll respond only to this last point (for the sake of a clearer 
discussion) because it actually contains the main issue (my code 'wish')...
...yes :) aligned_storage and placement new (plus the few additional 
workarounds for 'quirky' cases) are exactly/all i want...but because it is a 
relatively often used idiom i would like not to have to write it all manually 
every time...but rather have small class that wraps it up and allows me to call 
construct() and destruct() (with boost::in_place support and even the 'bool' 
left in debug builds for asserting correct usage)...
