[routing-wg]The sands of time...
by Rob Evans 26 Aug '08

26 Aug '08

...or maybe just the sands of the UAE. It is that time where I ask all you lovely people what you would like to talk about at the upcoming routing working group meeting in Dubai. Any ideas? Even better if you volunteer! Remember that the schedule for the Dubai meeting is a little different to usual, so that whilst we are almost back in our traditional slot, Thursday is on Wednesday, and the lunch that day is short as we have to leave for ou journey into the Arabian desert. If none of that made sense, the meeting plan is here: <http://www.ripe.net/ripe/meetings/ripe-57/meeting-plan.html> All the best, Rob
