I would say several things here.
1. The implementation of DDE in ActivePython is very poor, and doesn't do
very much. In particular, it is very incomplete.
2. Unfortunately, the DDEML library (Microsoft's canonical implementation
of DDE) is also poor and contains serious bugs.
3. DDE has a number of potentially crippling faults, but it is quite wrong
to describe it as a damaging zombie. When used correctly, it works
4. DDE is the only well behaved and reliable way to push dynamically
updating data into Excel (this is a *very* long story).

On the other hand, I concur with Alex: if you don't need to use it, don't.
Particularly if you're planning to write your own server: it's quite a lot
harder to get it right than meets the eye at first.
