Not only can it be done, but they can all run at the same time.

Vegas 4.0 through 6.0
==================
Vegas 6.0 and older (not sure about 3.0 and prior) will ask to install Microsoft .NET Framework 1.1, stop and exit.
DO THIS BEFORE INSTALLING VEGAS:
The trick is getting .NET Framework 1.1 installed. It won't install properly from the stock Microsoft download. Follow the instructions below very carefully and it will install (even though it will report an error or two):

Step 5 above is critical. Make sure you open the command prompt as Administrator. Click on the link in step 5 if you don't know how to do this.
Now install Vegas -- ANOTHER CRITICAL STEP is to launch the Vegas installation with Administrative privilege!!! Right-click on the install file and select "Run as Administrator".
I'm not saying everything will work perfectly, but you should be able to get it to run. I haven't experimented with Firewire yet on these legacy versions--and I probably won't bother.
