Are you a developer based in Portugal? I'll be in Lisbon on 13 November for the Codebits conference. I'll be there a day early (12 November) if you'd like to meet for coffee, or have me brief your team on Amazon Web Services, etc. Simply add your request to the AWS Evangelism Wiki at http://evangelists.wetpaint.com/page/MikeCulverEuropeFall2007.
Look forward to meeting you!
