Wow--lots of interest here. I'll weigh in as well.

I like the idea a lot, and have a guest house available in central PHX all year. (Maybe a whole house swap for that harbour view in OZ next August?) I've been registered with SERVAS all year, but no bites yet.

I would advise looking into the policies of organizations that do this, and have at least a suggested protocol, i.e. exchange passport number as part of swap, have a registration such as we have for OMNI, a boilerplate agreement, etc. More work for TalkBoard folk...

My hesitation would be commercial interests that would exploit the forum.
