Still wonder what's the issue with an el cheapo pre paid mobile card to provide some video/skype session. I mean is the US infrastructure even worse on mobile networks than it is in Germany (which is really not very advanced in broadband/high speed mobile networks compared to many Asian or other European countries, but getting a mobile to fluently do a video chat is not that difficult even in underdeveloped Germany...)?
And if the hotel does not provide the required infrastructure - change the hotel. I mean this is a computer party - a powerful net access is quite a prerequisite IMHO.
