           Summary: Constructing objects from a TypeId seems complex
           Product: ns-3
           Version: ns-3-dev
          Platform: All
        OS/Version: All

>From the code I am writing:

void AddWimetronetStack (Ptr<Node> node, NodeId nodeId, TypeId
terminalMobility)
{
[...]
      terminalMobilityStrategy = Ptr<wmrp::TerminalMobilityStrategy>
(dynamic_cast<wmrp::TerminalMobilityStrategy*> (terminalMobility.GetConstructor
()()), false);
[...]

So, given a TypeId, creating an object of that typeid seems rather more complex
than the average NS-3 programmer will be able to discern.  Good thing I am not
an average programmer, but I feel sorry for the poor souls that will need to do
this too :-)

A good candidate for a better API could be (for example):

Ptr<T> TypeId::CreateObject () const;
