I'm thinking about creating a gadget as opensource project for everyone to use which would enable developers to add feature they're web apps user profiles where user can simply add to his/her profile activity stream from stack exchange websites by entering uid. Like
format:
{User asked question} | title | url | timeago | Q&A votes | answer count
{user gave answered} | title | Q url | timeago | Q&A votes | answer count
and so for example last 10 items.
I have seen similar ideas come and go but haven't yet found anything under active development. So my question is did I missed out something and is there something already out there like that. Just don't want to waste time to re inventing the wheel.

And just to note that it should be quit auth free to enable also show streams from other accounts which activity you like or support
