[Sage] Is there any way to tie in Sage to the "Choose Feed Reader" option in Firefox 2.0b1?

[unkerjay]

I'm guessing this is going to be a permanent fixture in
Firefox 2.0.  I'm not sure if or how much it's going to
change between now and final release.

In the meantime, I'd like to be able to choose Sage.

It appears to only have an option for external rather
than integrated readers such as Sage or Wizz for
example.

Is there a workaround for this?

Thanx.
