Never, WebSockets is by definition TCP. :-)

However, there is already a UDP feature being specified, as part of

Both WebSockets and the data UDP media stream described above require that 
the receiving peer explicitly opt-in to the connection, so that we can 
prevent people from writing Web pages that connect to arbitrary remote 
servers like SMTP servers (to send spam) or anything else (e.g. to 
propagate malware/worms). There are no current plans to allow Web pages to 
have access to raw sockets, either TCP or UDP.
