You can open any stream by name. It's


C:\Users\Darren\Desktop>echo hello >hello.txt
C:\Users\Darren\Desktop>echo goodbye >hello.txt:goodbye.txt
C:\Users\Darren\Desktop>type hello.txt
hello
C:\Users\Darren\Desktop>more < hello.txt:goodbye.txt
goodbye

Of course, yes, to get a list of what streams are out there, you need API calls.

Yes. As is true of Linux's extended attributes and Mac's file forks, too.

Yep.

If you're malicious and don't care if you get caught after the fact, and the 
person you're pulling this trick on doesn't know about ADS, then yes, this 
can happen.

Now that you know, go download the free program that scans your disk and 
finds your ADS's for you, and you don't have to worry any more. :-)

I believe ext2 puts an upper limit on how much you can store in ADS. 
Something like 64K IIRC.
