I've seen services written with NTSvc.ocx, but they also seemed to suffer from
some flakiness. They were /not/ impossible to shut down, but on occasion would
hiccup and need to be "kill.exe" killed. This might have been due to Winsock
issues at the time and a poor, bottlenecked design, though.

* Does a scheduled task run without the user having to be logged in? Maybe you
could leverage that somehow.
* I've heard of a utility that will run an application on boot - can't remember
where. I wonder if there is some way to use the system.ini like so:

[boot]
shell=Explorer.exe %Windows%\YourApplication.exe

I'm not sure if this applies to XP, but have you looked at the
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices registry key too? I
believe you can point these keys to .exe files that are not actually services
<<< may be Win '95 specific info. You might be able to wrap the command line
with the RUNAS.EXE application to provide it a security context.
