Really, you can't. Netflix only serves the US, and Canada.
With a US account, you definitely need a shipping address because they need a place to send your DVD/BD rentals. Canadian customers can do streaming-only, but they have less titles available at this time.
Even if you could get by that, their streaming service only allow US/CA IP addresses to access their servers. It might be possible to get a VPN with a US end-point, but that'll hurt performance pretty badly. Really, even without the VPN what kind of sustained connection can you maintain to US servers? Netflix HD needs 3+ Mbps.
Really, you can't.
