What exactly limits the transport option to only " http request" ? 
AFAIK, the RemObjects library comes with a bunch of them, but supposedly only a subset can be used from within a browser: obviously " http request" but none else ?

As said it would be a nice addition to enhance their TCP/IP transport to WebSockets, to allow for a full duplex communication.
