Windows Phone Thoughts: What Questions Should I Ask Skype?

I'll be speaking with someone from Skype soon for an article I'm working on. While I have a list of questions that I'll be asking, I thought it might be cool to poll the community here and see if there's anything that YOU would like to ask. Regulatory issues, the future of VoIP, pricing - the sky's the limit, so please post your questions here - there's a pretty good chance that they'll be answered!
