Host a modified KCW swf only, point back to Kaltura?

Hello. We do not have php ability with our hosting solution.

Also, we have been impressed with Kaltura's existing hosted solution (where Kaltura serves the videos, embeds the player and uploader, etc).

Is it possible for us to host a modified version of the KCW swf (and supporting lib files) in our solution, and use Kaltura's backend for storing/serving the videos?

I find this documentation lacking as throughout the site I either see how to use Kaltura's existing solution, or how to download the full php self-hosted solution to do whatever locally.

How can I run a hybrid - to which I only modify the swf/libs, I embed those tags on my page, and point back to Kaltura's hosted solution?

Again, no php will be available.

Thank you in advance.
