The DebianInstaller developers get together from time to time and work on the installer in person. We've first did this during DebConf3 in Oslo, then during the 2003 Oldenburg Developer's meeting, and at DebConf4 in Brazil, again in Oldenburg in 2004, at DebConf5 in Helsinki, and at Oldenburg in 2005. In January 2006 a special meeting was held in Spain to work on the graphical installer.

If this trend holds true, then we will meet at DebConf6 in Mexico.

Update: And again at DebConf9 in Spain! See WorkSessions/DebCamp9
