Ok, let's try to come to a closer point for both.

Uhmm... Since I think that doing the integration work all by myself is a 
bit of a pain (and will be really slow going),
the solution is really simple...

I basically need some methods (hopefully simple and fast ones) to do 
some stuff, and if they are not there, you can maybe
write them to help me, i hope.

This is what I would have done:

The aggregator has a "start" method which accepts a list made of tuples 
like  ('URL', EXTRA_OBJ)

So you can send it the feed object (the one in the tree view seen from 
the GUI) to the start method (or a list of, when you need to update more 
than one feed at a time).

Then my aggregator downloads and parses (to the raw structure from 
feeparser.parse() ) the feed, then it can do some work (now it just 
prints) like
inserting that stuff in a database or such.

Then it returns a deferred. ---- Now this is how it's done.

In the adapted version it would call the method that updates the GUI 
with the new feeds (maybe through the feed obj reference).

If you can point me to the sections of straw where this code is.

thx
