What you can do is watch twitch videos where example projects are explained. Atleast there is a very good twitch proadcast about multyplayer shootout project. But the overall answer is no, you canno’t get that content without downloading them. You could just go to your brothers place and download them all there.
So to answer my own question and for anyone else in the same position.
Download to PC with unlimited internet access and transfer to USB. Move to target PC
Simply copy from the USB straight into the vault cache wherever that is on the target PC.
The issues I was wondering about due to reading other posts were:
Will I need to reinstall the engine - No.
Does it care that the locations of the vault on the two PCs is different - apparently not.
Did I have to transfer Program Data files - No.
Did I have to make a fake location - No.
I would recommend changing your ISP if possible but if not try to work something out with your ISP. If Comcast I have nothing better to say besides run as fast as you can out of there stonge hold area. But if all else fails start the download at the last hour or so of the data reset to get near double data
