It seems that the standard stream notation is "::".  programs like 
Notepad can
read and write to NTFS streams using the :: (double colon notation).  That
would seem to indicate thay are valid pathnames that describe a "file" 
of data.
I.e. -- ":" is valid in a pathname on an NTFS file system to indicate a 
stream.

":" also is a valid chacter on linux.  Sounds like a built-in 
incompatibility.

Note, that if you do a dir of file::stream, it won't showup, but you can 
open it,
so if cygwin implements the "open" call by first calling "dir" it will fail.
