This is possible through the use of a debugger. I've never used it, but 
I heard good thing of winpdb which has remote debugging. 
(http://winpdb.org/)

Another tool that I've never used is rconsole, part of rfoo library, 
which appears to be similar to pdm; it is also intended for the same 
kind of problem, managing long-running-processes/daemons.
