Found this site through Blender.org. You can showcase your .OBJ files with rotate, move and scale without the use of any plugins or add-ons. Free registration. Go to p3d.in
Sounds cool. Have you tryied it? I whonder how many polies it can handle. The model on the site is very small.
Are there more examples?
Here’s one that I uploaded, Open with google chrome or firefox, http://p3d.in/UmMZR
it is quite small too, polycount no matter, I think the cap at the moment is 50meg size obj… Hoping they add more later, also in the future is materials/textures, full details in http://p3d.in/faq

Diffuse, Normal and Specular texture support has been added together with a bunch of other new features
Awesome work bro, it looks like it works great 
I gotta give it a test drive.

p3d.in has been redesigned for greater flexibility and customization. 100s of improvements, new features and optimizations have been added resulting in a release that frankly makes the previous versions look unusable!
Check out the new Interactive model uploader & editor
