Hoi,
Use skype if international phone call charges are an issue. Many
people working on Wikipedia (and other wikis) use it intensively ..
I am sympatethic towards using Skype (or equivalent more open
VoIP-standards) in general, but I'm afraid that setting Skype
communication as a requirement for participation for interviewing will
skew the respondents in much the same way that only interviewing US
residents would.
