In recent years, IEEE Infocom (www.ieee-infocom.org) and the spring IETF meeting have clashed repeatedly, including this year. IEEE Infocom is scheduled several years in advance (through 2004 at this point), so it is easy to avoid. I've brought up the topic in the past, but was told that the number of people that were affected by this was just one or two, so it's just one more of a thousand scheduling conflicts. From conversations in Israel, it seems that the number of people affected has grown substantially in the last few years. I'd like to have a better idea whether this is indeed a real problem affecting core IETF contributors, and assuming that this is indeed more than a peripheral problem, at least let the IETF scheduling folks know about it. Thus, please let me know if you are or have been affected by this scheduling conflict. Thanks for your help. Henning -- Henning Schulzrinne http://www.cs.columbia.edu/~hgs
