Although you should not depend on 
boost::numeric::ublas::vector<double> iterators being implemented 
with pointers, you could do this:

// IDL
typedef sequence<double> DblSeq;

// C++
boost::numeric::ublas::vector<double> aVector(4)

DblSeq seq;
seq.replace(aVector.size(), aVector.size(), aVector.begin(), 0);

The CORBA sequence also has a similar constructor.
