Looking for TV model shipped with hackable FIRMWARE

[lambda79]

Hi everyone
I need to buy a tv 'customizable' enough to get features working like:
- having a browser inside for viewing web pages
- having smbmount (or similar apps) working to map network drive from a samba server
- viewing office application documents (like .odt or .doc files) and displaying to the screen

Do you by any chance know a firmware version(whatever the TV model is) open enough to have samygo app and/or root access and shipped with a TV new enough to buy it from a retailer?

any hints very welcome, i plan to setup a mass TV deployement (30 tv) and i am looking for knowledgeable techXpert

I don't need 3D at all, i am posting in D series forum but do not avoid relevant devices from other series if they are relevant enough to be exploited.

thx you
