It is quite small, and many consumers of your presentation might not even notice it. But then again, maybe they will. You can replace the Adobe logo with your own by doing a little bit of setup work.
First, create a SWF file of the logo you would like to use on the playbar in place of the Adobe logo. The size of the replacement logo must be 47 pixels wide x 27 pixels high. Give the new SWF the following name: logo.swf.
Save the new logo.swf file in the Adobe Templates folder (replace the existing logo.swf file). A typical path to that folder might be c:\Program Files (x86)\Adobe\Adobe Presenter 9.0\Templates
With your presentation open in PowerPoint, use the Publish tool on the Adobe Presenter tab to publish the presentation.
And just like that, your logo will replace the Adobe logo on the published playbar.
