I'd be interested in the thoughts of others, but I've settled on a VPN back to my home router than can only see outwards, so not a way into my home network. Quite a few home or small business devices will let you do this. Browsing and other activities can be affected by the consumer grade network to home and back, but its generally usable.

As discussed above I don't use it for most browsing, but for anything that likes me to be at home I can fire it up.
