[webkit-dev] Announcing WebKit for Wayland

[Benjamin Poulain]

Hi Žan,

Thanks for announcing this project here.

Can you explain a bit why you decided to use the UIProcess directly 
inside the compositor?

I am a bit concerned about the security of this model because the 
UIProcess becomes an attack vector for the compositor. Sharing the 
memory space with the compositor would prevent aggressive sandboxing.

Great Wayland support seems like an important target for WebKit on 
Linux. Do you know what are the plans for GTK and EFL?

Benjamin
