It's the usual difference which has already been discussed on this
list.  Login in with password auth -> share access, login w/o password
-> no share access.

Did you rsh using password auth or rhosts auth?  If you used password
auth, the problem is a more general problem and isn't really related
to the authentication method.  The difference between stdio redirection
works and touch doesn't work is weird.  Perhaps an strace of the 
stdio redirection shows you the difference.

Btw., in your strace one can see that it's actually Windows which 
denies access to the file, not Cygwin.
