"IETF 80":http://www.ietf.org/meeting/80/ will be held in Prague - and as a early bird I registered today. The advantage of Prague is that I am familiar with the city which makes it easy for me to find a cheaper hotel compared to the standard conference hotels (Hilton: 148 Euro/day, Inter Continental: 140 Euro/day). The hotel in Beijing ("IETF 79":http://www.ietf.org/meeting/79/) for example costed ~1500.- Euro for 9 days. I hope to find a hotel for about 350.- Euro. Looking forward to meet colleagues and IETF maillinglist parter.
