Using PC plugins on a Mac....HELP!!!, Can I use VST PC Plugins on my new G4 Options

I just purchased a MAC G4 Dual 450/640mb, ect. I also have a pc with a SHITLOAD of PLUGINS.
For Example, Native Waves GOld Bundle, Time Bandit, Orange Vocoder, Tc Electronics Plug-ins, Bitheadz Pharazer, Native Pro52 model synth, Tons of VST/ DirectX plugins, Waldorf Attack, Steinberg Model E, Alboretu-Hyperism, Steinberg Mastering edition, Waldorf PPG Wave V2, Prosoniq Time Factory, Ect. I would never have enough room to list them all.
I am using Cubase VST 5 for sequencer. I know I will probably have to buy the Mac version for cubase for it to run on the mac, because I don't think the pc version will run on the mac. My question is if I buy the Mac version of Cubase could I use all of these plug-ins with the mac version of cubase just by transferring the plug-ins from my pc to my mac. Or is there a seperate version(mac and pc) for these plug-ins.
I though that plug-ins can be used on either platform as long as the sequencer that is using them is for that specific platform. If you can help with this question in any way I would greatly appreciate it. I would hate to have to buy all new mac versions of these plug-ins(over $5,000).

Not to sure about the VST ones as I do not use Cubase on the Mac, I think that software companys develop 'versions' of the plugins for each platform.

I would imagine that the PC VST ones will not work as they are .dll libary files and I would imagine Macs have there own version of the .dll file (Not a Mac user until Friday)

Your DirectX plugins will not work as DirectX is a PC only thing (as far as I am aware), unless there is some type of convertor.

You are right in assuming that your VST PC version will not run on the Mac and you will have to buy a new version, though if you are moving to Mac then I have been told that Logic or Digital Performer will be your best bet, your plugins will also work if you get the Mac VST versions on both programs (though you will need a program like VST Wrapper for running them in DP)

One option you might have is to contact the manufactures of all your plugins and you might be able to send in all your S/N's and they might give you a special upgrade/crossgrade price.

Hope this helps,
