I doubt anyone on HN would pay for a service like UFlix when the DIY alternative is much more efficient. For less cost we use our own US-based vps, running something like the shadowsocks proxy. It's the same rig we found to work the best in China against the great firewall. With its own dedicated IP, it would likely be cost-inefficient for Netflix to detect without blocking an entire range of legitimate IP addresses.
They've blocked pretty much all hosting providers and vpn provider's ip ranges.
unless you get an ip in a residential or possibly university range... you're pretty screwed.
