This sounds okay. You just have to remember that the sequence you return
from EchoList::getEchos() will be freed by the ORB (using delete), so it
MUST be heap allocated, and you must not hold onto that pointer.

I assume you're doing something like:

Echoseq*
EchoList_i::getEchos()
{
  Echoseq* seq = new Echoseq();

  ... initialise the sequence ...
  ... store <seq> somewhere ...

  return new Echoseq(*seq);
}

This will duplicate the references to the Echo objects appropriately.
