Each of the examples codes previously cited do not prevent you from handling 
data how you want to.  You can grab the relavent parts of those examples for 
setting up a client.

Another example can be found in ParaView3/Servers/ServerManager/Testing/Cxx,
or the pvpython client in ParaView3/Utilities/VTKPythonWrapping/Executable

Not really.

Fetching data in C++ can be done using 
<http://www.paraview.org/ParaView3/Doc/Nightly/html/classvtkSMBlockDeliveryRepresentationProxy.html>
or
<http://www.paraview.org/ParaView3/Doc/Nightly/html/classvtkSMClientDeliveryRepresentationProxy.html>
and probably some other ways too.

You can see how "Fetch()" is implemented in that python script by looking in
ParaView3/Utilities/VTKPythonWrapping/paraview/servermanager.py
