For anyone interested, all demos from the DreamHack Winter 2015 TF2 Invitational are available at:
http://lyngby2.devrandom.dk/demos/
SourceTV demos are available in srctv/ and prec KillStreaks.txt files are available in the killstreaks/ folder. I havent't tried catagorizing the killstreaks, but the number in the filename corresponds to the computer number in the in-eye demo filenames.
The entire bundle is also available as a single-file download in the all.tar.xz file.

Some demos are missing because a few players deleted their demos when they copied them to their various flash drives.

Enjoy!
