Once you allow native code on a Windows machine, there is no limit to what it can access within its user rights, same 
with Unix. Even as a non root process any program can do a lot of obnoxious things.

Any native code compiled executeable, compiled DLL, complied plug-in or what have you that you run has the same risk. 
If you don't trust where you're getting it from, don't put it on your machine. It's something we take for granted on 
these platforms. 

Perhaps you are from a more interpreted environment where code runs in a virtual machine like Java, BASIC or Batch File 
programming.

I have concearns about the Plugin arhcitechture and the power given to all the devs out there and possible end user 
harm. I am writing the FastTrack plugin for Edonkey/Overnet and during this process have realized that this is by far 
the worst and most insecure plugin architechture I have ever seen in my life. Here is a short list of what they have 
given 1.14 million users(currently online) to have done on their machine if they are to download an "bad" plugin.

1. Local code execution
2. Unlimited disk access
3. Unlimited sockets access
4. Code propogation through the client over the networks
5. Basically anything you can imagine in the world that can be done to a windows os machine.
