Like many of us I was moved my Harald's appeal for suggestions for helping to cut down costs in the IETF.
I certainly endorse the idea of considering Canada or Mexico as possible sites for future IETF meetings, but I suspect that the weekly teleconferece calls that the IAB and IESG have represent a significant line item for the Secretariat.
In case anyone has not heard, SIP is quite capable of handling this type of task and there are a variety of commercial as well as open source Client User Agents as well as commercial products and services that could help reduce this cost.
I'm sure the SIP working group could help the Secretariat identify products and services that could make this essential function more productive and operate at less cost.
