[Googlebar] Are there any support for weblog posting other than Blogger?

[n-n]

Hi,
I want to post the current page link to MobavleType using Blogger 
botton(or similar one) in google toolbar.
Although there is a similar utility for MovableType, this way is more 
easy to use.
MovableType and Blogger moved to ATOM API for their remote access API. 
So it seems possible to have a customizable weblog posting botton(which 
is based on Atom API, and can support any weblog using the api) based on 
current FireFox google toolbar extension.
I would like to know the current status for this direction.
Thanks,
