You've heard correctly. Even with ActiveX controls may be severely limited. As well -- depending on client OS and security settings -- the control may need to be signed by a trusted Certificate Authority. (You can create one on your network, but how to do that and configure the client correctly are a questions for server fault.)

Not sure that this can solve your problem, but a copule of days ago I found this utility: http://downloadify.info. That's solution which is mix of flash app and jquery plugin.

You could do this pretty easily by creating a FireBreath plugin; FireBreath makes it relatively easy to create plugins that work both as ActiveX Controls (IE) and NPAPI plugins (firefox). You're right that ActiveX controls are going to be the only way to do it.
