That is, you should use
zippedfile = open('%stemp/tempfile.zip' % settings.MEDIA_ROOT, 'wb+')
You might have to close and reopen the file, or maybe seek to the start... .
You should very probably open the file in binary mode, when writing zipped data into it .

I have a nice interface, and I want to implement one member of it in a base class so the clients can derive from the base class and have less boiler-plate to write. However, even though declared abstract, the compiler complains that the class does not...

TaskDefinitionBase needs to include CreateTask - if you don't want to implement it, just mark the method... .
You must add an abstract stub of the method:
public abstract ITask CreateTask(TaskId id);
Inheritors can then override it to implement the interface .

Problems like this are why I think solutions like boost::non_copyable are a bad idea - there are simpler ways of saying you don't want ... .
Firstly, remove the private derivation from SpecialFilter - it is not necessary, as Filter is already not copyable .
