You're missing the point of MTI. If H.261 is MTI, nothing prevents you 
from supporting VP8 and H.264 anyway. It is possible for mobile 
applications that interact with web clients to only need 
lower-resolution videos (think: accessibility applications). It is quite 
reasonable for them to only implement H.261 and no one will be harmed 
because specialized applications are not meant to act as generic web 
browsers.
