HOWTO: Export or Backup content from WordPress.com?

so far there is no any possibility to export all posts (not just recent ones), not speaking about of exporting comments to them. I am still wondering whether that light future ever shall become? cause if it wont — WordPress.com can’t be considered as a serious blogging service: no backups, no chance to transfer content to self hosted blog in the future.
currently you can export text of all articles as an RSS feed. images and other attachments uploaded to WP.com and linked to articles should be downloaded manually. still, I do not know how to export: static Pages, Category and Links structures; import: comments.
