Sure, why not. I've done many now via skype and email. I live with two partners raising a child and have two others. I have been identifing as poly for about 14 years.
Might I suggest in addition to interviewing people that you have a good read around here on people's lives. Have a look in the search engine for tags that interest you. Maybe you will have your questions answered in different ways or confirmed as a result.
Anyone want to be friends on Facebook?
