User Connection speed test *before* page load?

I have an idea for a site, but it's bandwidth/p开发者_如何学运维rocessor heavy.

You can see (or not see) it here: marckremers.com

Basically, it's 6 webcasts all playing at once, i cant think of a better way to show potential clients a visually enjoyable and dynamic overview then this. Websites aren't static, I want to show my UIs and designs being used! Not showing 'dumb' stills.

But it's processor and bandwidth heavy. I'm wondering if there is a good way to test the users speed first, so if their speed is up to it, I can show them the bells and whistles moving version, if their connection is slow, they get the basic which they can still play if they want.

Doing speed connection tests is kinda old school and not desirable, but I think it's warranted for this kind of presentation angle.

I've googled around but there doesn't seem to be anything out their that's accurate.

Also wondering if there is a different way of doing it, like timing the play buttons to start sequentially?

I would let the users decide. Speed and processor tests are possible, but they take time.

For what it's worth though, I find the six webcasts running in parallel rather annoying. I would use static images, and show the animations on click or something.
