The topic you posted is not exactly the same as asked here. I already thought about this, it whould be possible but I think not ingame. You whould need a external loader AND you whould have to host the updates on a fileserver. AND there whould be ALOT traffic going on there. We got over 5000 sitehits at this site PER DAY. And its only from the ppl who read this forum. But this version is posted on many warezsites and in a lot changed/modified versions. And everytime a user starts the game and checks for updates there will be a connection to that host to check for a version. I don´t think that a Filehoster will take that much traffic without extra payment.
