[AusNOG] Australian Steam Content Mirrors

[Cameron Daniel]

Absolutely correct.

Last time I spoke to Valve about Steam content (at a previous employer) 
they were pretty open about how it's being delivered and how it can be 
cached if you want to go that route.

That said, you should be able to pick up a reasonable portion of it 
through Highwinds if you're on any of the IXPs (Megaport, NSW-IX, PIPE, 
Equinix).
