embedding strategies; C++ server

[Randy Heiland]

I have a scenario where I have a "black box" (C++) server that executes
"arbitrary" Python commands (strings) handed to it.  Consider the
following hypothetical situation:

client:  cmd = "init"
server:  Py_Initialize();

client:  cmd = "from geometry2D import *"
server:  PyRun_SimpleString(cmd);

client:  cmd = "square = Quad(0,0, 1,0, 1,1, 0,1)"
server:  PyRun_SimpleString(cmd);

client:  cmd = "square.GetPoints()"
server:  <detects that "GetPoints" is being invoked and
obtains/processes
              the actual points in C/C++>

Which embedding strategy lets me do this last step in the server? (any?)

thanks,
