Actualy a combination of all four would be nice.

But I would prefer "In-depth technical conferences aim at developers."

It would be very nice to have such events in Amsterdam and/or better in Utrecht (Most central city of The Netherlands)

I am interested in In-depth technical conferences aim at developers.
I live in Saint-Petersburg, Russia. Good places are Helsinki, Tallinn, Riga, Stockholm also (Baltic sea region).

I would like to see a vision of where Skype are going with their core products so that developers can make educated choices and where to spend their efforts and money. This would provide a chance to compliment Skype and not compete.

Although I'm not suggesting that Skype completely lifts their skirt sharing some future direction under NDA I would suggest would borrow some of the good practices delivered by other technology companies to their developer network.

I'd like to see you guys conduct a high level conference on the business benefits of Skype. I live in the Washington, DC area and a conference here would give you the chance to reach out to government, non-profit organizations and the growing for-profit sector, including many technology companies located in this region. If I can be of assistance, please let me know. Thanks!
