Dreamcast used a browser called "Netfront" by an Japanese company called "ACCESS".
SEGA just took the browser core and put some fancy User Interface and then called it "Dream Passport".
EGBrowser is nothing more than the Netfront browser stripped of the fancy interface it had on the Dreamcast.
Oh and the version on the PS2 is a slightly improved one.
