In this article I give an account of my cyberethnographic study of the International Women's University "Technology and Culture" (ifu) 2000 and the network its participants formed in the ifu's virtual extension, vifu. The article offers a description of the methodological considerations and challenges I was confronted with whilst carrying out this research. In addition, I explore these methodological considerations on a conceptual level. Primarily concerned with questions of home and belonging and the question of how these notions figure in contemporary mobile lives, I explore here how conducting online research became the only possible method to adequately reflect the "mobile" nature not only of the event ifu and its virtual extension vifu, but also the ways in which participants negotiate belonging and mobility in their respective worlds and to the (v)ifu network.
