I don't know, but maybe when we can install apps like we do it in Wii with the channels, it will be a launcher in an app so that app will have that support, I think it will work like Wii The Homebrew Channel.
Due to the nature of the Webkit exploit, I don't think this will be do able. At least not with that exploit alone. We would first need to gain access to a lot more of the consoles hardware, then we would need a way to somehow fudge the RSA signature for installing said channel (unless of course we have the necessary private keys ). Then we would need to be able to pass the RSA signature check, everytime said channel is launched. The best thing for that would be to have the actual private keys to sign it properly so we don't have to fudge the signature at all. Fakesigning would be super easy for nintendo to pick up on and patch. If we have all the private keys, then nintendo won't be able to tell the difference between homebrew signatures and official one's as they will be identical. They would have to use another approach to block/remove such a channel.
We're still a long shot away from all of this, but the scene is looking brighter and brighter everyday . Things are picking up all the sudden and rapidly .
I could see the webkit exploit eventually being used to trigger other exploits down the road that would allow us to install such a channel, but for now, this is all we have
