NetOp Remote Control from Danware Data should suit you perfectly. It's possible with this app to make the host program (to receive incoming requests) load automatically at bootup and to make it hidden from systray.
(The program name still shows up at Task Manager in XP,2k and 2k3 however this is usually inevitable. I'm not sure about Win9x task manager).
It's a reliable and highly customizable app.

HTH + Cheers.
Stone walls do not a prison make,
Nor iron bars a cage;
Minds innocent and quiet take
That for an hermitage;
If I have freedom in my love,
And in my soul am free,
Angels alone that soar above
Enjoy such liberty. - Richard Lovelace
