Is it possible to filter your lifestream to just be your personal activity and then access that via an RSS feed? I'd love to replicate the lifestream concept on my blog and am currently redoing this all on my own as a WordPress plugin (don't like the existing ones) - but it would save a ton of time to use a better service at grabbing all my data, and then just using that feed to populate my data for my blog....

Thanks

PS - This concept would really require the ability to add _any_ RSS feed to your lifestream to support self-hosted blog sites, lesser known social sites/video sites/etc.
