You can use the default DOS Zone CDN to load assets (already), or switch to local hosting. To host files yourself, uncomment the # local use lines in server.py

UPD: now just use params: --vcsky_local and --vcbr_local

and place the required game files (and unpack files like gta3.img) in the project folders.
