To access your computer at home try one of these apps...
Mocha VNC Lite for iPhone, iPod touch, and iPad on the iTunes App Store
Desktop Connect for iPhone, iPod touch, and iPad on the iTunes App Store
As for accessing Netflix, you need a proxy service. I have heard that Netflix has closed this loophole, however I have not tried lately. I used to use
Hide My Ass! Free Proxy and Privacy Tools - Surf The Web Anonymously . Others have used proxykey.com.
Hope this helps.
