Currently, Google Chrome updates using a tool called 'Courgette'. It uses a complex delta compression algorithm to both compress and eliminate redundant data, as well as using a simple delta compressor. For those of you ho do not know, delta compression is when 2 people/computers have an old file file, and one of them has a similar file that they would like to send to the other person/computer (they don't have to be similar, but you get better compression if they are). In order to preserve bandwidth and download time, you can get rid of all the data that is already in the old file, because the recipient already has it. I'm suggesting that we have a launcher for TPT, integrated in the .exe, that updates using delta compression, but also lets you download a mod delta package, such that you could download and run a mod in one fell swoop.
