Has anyone come up with an easy way to enter a household, the members, create the relationship, share the address, etc.?
We have setup a webform which enables the creation (or updating existing information) of 

1) a household with its own data (phone number and physical/mailing address)

2) one or two adults with their own data (defaulting to our Spouse/Spouse relationship) and makes them share the address of the Household

3) 1-5 children with their own data who share the address of the Household and allows you to choose the relationship to Adults 1 and 2

The length of the Node Export was more than Stack Exchange allowed me to paste in, so you can find the CSV here: https://www.dropbox.com/s/e4vw5a9o15c1aiz/node-export-household-and-family-webform.drupal?dl=0

I don't know how this would work with importing back into your system with Node Export given that we'll have different relationships and tags and slightly different needs, but I think this will get you on the way.
