I don't personally Stealth Tether via this route, I use:
Tom_Codon CM Wifi Internet Sharing (for Wifi, obviously)
(Some Internet Share program) (For USB)
However, since my laptop is down and out right now, and I am using a PC that came with Win98 (upgraded to XP Pro SP2), USB is currently my only option (however it works, so no complaints here).
