Parameter to hide the download or and fullscreen option in the Office Live viewer

I am want to display a PowerPoint document (well, to be honest i don’t but my client’s wants) in webpage. I found the office viewer. The only thing I am missing is that I want being able to disable the download button. I googled around but couldn’t find any sample or list of available parameters.

Any idea ?

Its a webpage so embed it into an iframe an write some JavaScript to remove it.
