use unicode fonts for ur site.like- AksharYogini.ttf
gargi.ttf lohit_hi.ttf sahadeva.ttf Sarai_07.ttf chandas1-2.ttf kalimati.ttf nakula.ttf samanata.ttf etc
it works on all operating systems including non-windows.
but what @satyam told is true.I have seen a website in Malayalam,which renders the fonts without the fonts installed.
it showed some "MMOnline.dll" and this works only with windows operating systems.they call it as "dynamic fonts"
see their FAQ:
