If the plan is to have a WineConf on September 19th, we're now within the 6 month window. Is there anything I can do to help? Oxford or Reading still gets my vote. Also, I just noticed there's a LinuxWorld Expo in London on October 25-26. That's getting pretty late in the year, so I'm not sure if we should coordinate with that at all. Personally, I doubt I could make a conference any time after September.
Also, there's an O'Reilly conference, EuroOSCON, September 18-21 in Brussels. I might be able to make some calls to people I know with O'Reilly and see if we could dovetail in that conference to use the same hotel space the weekend before - September 16 & 17th.
