You can achieve this by creating a simple wrapper class derived from
Component, overloading virtual void ClientBase::send( Tag* tag ).

The rules are pretty simple:
Never delete a Tag/Stanza you received from any handler.
Never delete a Tag/Stanza you sent off using ClientBase::send() (or similar).
If you delete a Tag/Stanza manually, only delete the root Tag/Stanza. It will
delete all its children in its dtor.

Yes, these seem reasonable. I'll add them in one of the next (pre-)releases.

This one is in 0.9 already.
