PLUG-INS!!! Surely somebody knows!, TDM / RTAS / VST - MacAmp / SoundJAM?? Options

I own a ProTools (MIX/TDM) rig & have a ton of plugins. Is there a way to use plugins OUTSIDE the ProTools platform?

I'm trying to find a way to add compression / L1 type maximization to a streaming audio web-feed. MacAmp has a few plugins, but nothing much. Is there a way to ADD plugins to MacAmp or Soundjam - or some other mp3 player?

Is there a way to use plugins as if they were rack gear & route other programs into them? Didn't Waves have a way to do this once upon a time?

    That should be easy too, provided that one has not disabled or removed the internal sound card that comes with your Mac.  I am not totally sure on this one because I have never had occasion to use MacAmp, but my experience has shown me that a Mac loaded with the proper memory can do double duty.  When I took delivery on my Pro Tools HD 3 System, I was required to instal proprietary hardware inside the G4.  Then I needed a compact disc mastering program that would utilize the CD burner that came shipped with the G4.  The only one I knew of at the time was WaveBurner Pro 2.2, which came highly recommended to me by peers.
    Well, to my surprise and dismay, WaveBurner at this stage of the game, does not recognize the Digidesign High Definition audio interfaces.  When I rang up tech support at eMagic about this, they politely informed me that HD was 'too new', even though I have had the system since January, and it says right on the box that it can be used with all TDM systems.
    My only option was to use the internal Media sound card that already comes standard with the G4.  I felt silly taking a stereo mini-plug output into balanced XLR inputs of my monitoring system, but it was either that or shippping it back in favor of Master List and buying an external burner (which by the way does have it's advantages).
    This splendid little inconvenience turned out to be somewhat of a bonus, in that I can actually run both applications at the same time.  I can switch back and forth between monitoring Pro Tools or WaveBurner without having to shut one program down to open another.  I can even monitor both of them simultaneously if I so choose.
    I will bite the bullet for now until there is and upgrade which will someday let me hear WaveBurner Pro through the glorious high fidelity of my 192 I/O interfaces. The Mac Media sound is not the best thing to use, especially in the case of mastering applications, but it is certainly not the worst.  OK, I have to bump up the level somehow from -10 to +4, but how bad can it be for processing Mp3 audio?  If you put audio in and stream it out, then in theory, it should work.
