The Supermondays group is a regular meetup of various technical people in the North East of England, and I'll be speaking at their PHP feature night about using PHP with web services - something I do a lot! This is a new crowd for me and also interesting to bring PHP technology ideas to a crowd that is technical without being PHP-specific.
