I apologize for not having followed this discussion more closely.
Whatever you do, please do keep in mind that vector<bool> breaks most 
(all?) standard assumptions in various ways and there are known DRs
for those with endless discussions.  Whatever you do, please make sure
that the standard semantics are fullfilled and remember that
vector<bool> just is in outerspace.
