I was thinking of something along the same lines the other day, but was 
thinking of using the same protocol that is used in VNC,

   http://en.wikipedia.org/wiki/VNC

The protocol,

A simple counter example,

The main reason I was thinking along this path in the first place was a 
way to get around the Element Manager problem that you see with network 
equipment needing to run a special client program which is one reason a 
lot of these companies are reaching for Web Application. This, as you 
know, introduces a new set of problems to do with supporting different 
browsers which leads companies to mandate the use of one browser so this 
is really a false solution. What I'm proposing here is that the client 
machine run a VNC client, and there's plenty of free ones available, and 
that the network device/server/etc runs a VNC server. This way it is 
possible to control the look and feel, etc without the bloated browser 
stack and its problems. This argument would be valid for most thin 
client protocols, but I think the VNC is one of the more suitable ones.

It also gives interaction which you for see as a problem with your method.
