I think the point we're missing is who is "I" in "If I would like this program to start in demo mode". You're saying that you want a setup where you fire up the server in one mode or the other, and everyone who accesses the page gets the one same mode depending on how you start the server? Well that's pretty easy, you could for instance use servlet parameters specified in your web.xml file. Here's a random google webpage with code for that: http://www.exampledepot.com/egs/javax.servlet/GetInit.html
More normal, and a good use of deferred binding, would be to have two slightly different addresses, one for demo and one for normal mode, so you can just point people to the appropriate site and not have to restart the server every time you want to change the mode everyone sees. If you do that, you could pass a parameter to your server RPC calls indicating that the client is running in one mode or the other to have the server respond with the correct stuff.
