Hmm. I've read those posts, and never did find a resolution.

There's a thread "connect to running python COM server", which ends 
with code from Andy that doesn't look to me like it would really 
create a singleton (it looks like it would only allow one instance 
within a process, but not one instance on a machine). Does it work?

There's also a thread "I'm BaaaAAAAAAaaaaaaak" where you find some 
code (horribly trashed by being posted with leading tabs and getting 
htmlized) that appears to try to use Policy objects to create a 
singleton. Again, to me it looks like it would work in-process, but 
not machine wide.

I have had success with using the ROT, which is very easy to do. 
Unfortunately, if I leave the (singleton) server running for an 
extended period of time (say 6 to 24 hrs), at some point I find my 
machine locked up. This is NT 4 SP4 on a _very_ stable machine - the 
only BSODs I've ever seen were when I had a parallel port Zip disk 
attached. (I moved the Zip disk to my Linux box, where it's performed 
flawlessly ever since :-)).
