Any XSL-FO browser implementations?

I was wondering if any list member was aware of any browser which was able to 
display any XSL-FO natively. I am not necessarily seeking any full 
implementation. A partial implementation would also be of interest.

If agreeing to an NDA would gain access to any alpha or beta code then I 
would be happy to accept that.

Any replies on and off list would be appreciated.
