In short, you could create a website which saves changes to itself straight to the safe network via a javascript library.
This sort of dynamic site can be done without server side scripting, as the client itself can load/save data directly to safe net.
In theory, if it is your own site, you should already be authenticated by the launcher and making changes should be simple.
This is a shift in software design approach, but one which we have been moving closer to for some time in web development. Safe net will make this approach a natural one.
