I think you're right, it wouldn't be _too_ hard to allow PSPs to extend
other PSPs. You're welcome to try... I'm not likely to try any time soon.
What would be even cooler is if we could come up with a way for a Python
servlet to be derived from a PSP to make it fully general. Random thought,
without looking at the PSP code at all: Perhaps we would need to expose a
PSPFactory:
from PSP.PSPFactory import PSPFactory
# This returns the Python class corresponding to MyPSP.psp
MyPSP = PSPFactory('MyPSP')
class MyServlet(MyPSP):
# override methods here...
I'm not sure if this is possible though.
