I have no more information as yet, expect to say that I saw someone asking a 
similar question somewhere else and they asked whether the RPC_CONNECT 
method could be used in HTML to spread this. Now I am not an HTML programmer 
let alone a C programmer so I have no idea whether that is feasible or not. 
However I would be very interested if it is as it could make a big 
difference to all of us. So any of the more knowledgable people out there, 
is there anyway that comes to mind that this exploit could work over port 
80? What about other programs that use DCOM and listen on other ports, are 
they vulnerable in theory? Would it require entirely new exploitcode for 
each package/port to be exploited?

By the way I am not asking for an exploit, I am neutral in the whole debate, 
just someone who knows what they are talking about to give us an idea of 
whether this thing is ever going to work over ports other then 135.
