Load flash movies directly from any source (no temporary files)+snap a frame

Hello, everybody!
As known, Flash Player is always copying swf file from I-net before playing it. But how can we load flash movies directly from any source without usage of temporary files to protect this swf from any other access? In my app I need to load flash movies directly from any source and get a snap image of the current flash movie frame run-time. Does anybody know technologies to do this?
Best regards

You may use F-IN-BOX - a powerful flash control.

It's not cotrol - it's library for developers. :)
