cakephp und google base / merchants

did anyone build a class for interacting with google base or google
merchants
like for publishing products etc.?

you can use the cake1.3 CakeSocket (or HttpSocket in cake1.2) to
connect to the account and its feed and POST the data.

i started to create a lib class for updating the feed via POST of an
xml-file
and thought maybe somebody else came up with something similar idea

gerenelly i can think of 2 different approaches
- behaviour which updates the feed in real time (afterSave and
afterDelete callbacks)
- cronjob which updates the feed frequently (full override with a
complete xml file of all products) - many companies do it this way

I might have to integrate it in an online shop
PS: if somebody is interested in working together (because he/she
needs it as well) feel free to contact me
