Hmmm, ok. Honestly I don't exactly know how those premier account work... In fact Erminig does not make any assumption concerning the location of the calendar server: it's all up to the google-data library. All what Erminig does is to pass the username/password couple to the Google Library, which then takes care to contact the Google servers. At the moment I have no idea how those premier accounts are managed Google-side...I will investigate this issue...
