OK, so I wrote my own InstallService:
That actually isn't necessary - the class can provide _exe_name_ and
_exe_args_ attributes to override the defaults.
See attached sample which works for me - be sure to place it in the same
directory as the pipeTestService.py sample (win32/Demos/service). I'm
afraid I did mislead you a little in the steps necessary to get things
going, but I'm checking this sample into pywin32 so it doesn't get lost
again :)

# This is an example of a service hosted by python.exe rather than
# pythonservice.exe.
# Note that it is very rare that using python.exe is a better option
# than the default pythonservice.exe - the latter has better error handling
# so that if Python itself can't be initialized or there are very early
# import errors, you will get error details written to the event log. When
# using python.exe instead, you are forced to wait for the interpreter startup
# and imports to succeed before you are able to effectively setup your own
# error handling.
# So in short, please make sure you *really* want to do this, otherwise just
# stick with the default.
