1. Open your PowerPoint file.
2. Save it as a web page (File >> Save as Web page...)
3. In the 2nd window, in the Save as Type field, make sure to select Single File Web Page.
4. Click Save. (You will now have an .mhtml file)
5. Now, in Blue Voda, Insert an Iframe on your page and resize as required.
6. Copy this code:
<style type="text/css">
body {background-color: transparent}
</style>

7. Right-click on the BlueVoda page and select Page HTML.
8. Select the Between Head Tag tab.
9. Paste the code (from step 6 above).
10. Click the OK button.
11. Now double-click the Iframe.
12. Give the Iframe a name.
13. In the URL field, type the url, e.g. http://www.yourowndomainname.com/presentationname.mht

(only use .mht for the powerpoint web page presentation extension).
14. Upload the new PowerPoint web page to your site by using the FTP manager (in the Tools menu) OR use this tip:
a. Click on the File Publisher button in BlueVoda.
b. Double-click the shape inserted on the page.
c. Click the Add button.
d. Browse to and select your PowerPoint web page.
e. Click the Open button.
f. Click the OK button. (This procedure will automatically upload files (e.g. your selected PowerPoint web page) during publishing, instead of using the FTP).

15. Save your BlueVoda page.
16. Publish the page.

When you view your page, you will see the presentation where the Iframe was located. You can view the presentation using the Outline tree, the next/back buttons or click the SLIDE SHOW button.

It works quite well and I hope this will help you. There might be other options, but this one works.
