In _winreg.ConnectRegistry() it says:

computer_name is the name of the remote computer, of 
the form "\\computername". If None, the local computer 
is used. 

Could it be changed to use r"\\computername"? (it just 
took me half an hour to figure out why it couldn't find the 
computer on the network, and I really should know 
better :-)

Tim, can you tell me what the right thing is?  I don't have
enough Windows Registry Zen to know.  Feel free to assign
back to me for action.

Ya, this is just the usual business of "how do you spell a 
string that's supposed to have two adjacent backslashes"?  
Using an r-string is indeed easiest.  Using a regular string 
literal with 4 adjacent backslashes would also work.  It's 
really got nothing to do with Windows, except that MS has 
this irritating convention of using backslashes in assorted 
network names.  Back to you, Fred -- happy to be of 
service <wink>.

Fixed.
