Just to mention it here I suggest in the long run one might take a look at 
chandler (calendar application) entirely written in wxpython it's designed to 
avoid a lot of problems. Does iCal as far as I can see plus it is wxpython.
Should be easy to nterface.

But hey. Oscar is there already so chandler is more like an long term option
