Social bar (Facebook, Twitter and Google Buzz ) in my presentation

Hi guys :
I´m working on a beta version of a bar to share my articuate presentation. I put all my presentations on my wordpress blog, but I was thinking how the people that watch them can share them in a easy way.

Well a picture with my idea and a link where you can take the files and make some test if you want.

Info and sample here ( spanish only ) :
