New photo events for Picasa

Question

Presently I pull list of Picasa photos every 5 seconds using Google Data API - and compare against an old list. When new files are added, e.g. 'sync'ed from Android device or uploaded by user using Google+, I may experience a lag (e.g. 5 seconds) before realizing the new photo and download/process it on my machine.

Does Picasa have a event model where it "pushes" news of a new photo using some API?

There's no subscribe/push. But, using the feed can be optimized with a minimal query: only get the last item (max-results = 1) with minimal fields. Then, if there's new content, go and fetch it as you already do.
