Gabcast, atom, blogger api, embed objects

Gabcast is a service where you can record podcasts. They give you the ability to automatically posts your podcast into your blog using wither blogger.api or atom. They also give you the ability to embed a glash player in the post if the blog software allows it.

My Questions:
1. is there a plug-in (or built-in) feature with WP to allow auto postings via atom.
2. Does WP allow object embeding in a post?
