  One of the strength of Virtual Organisations is their ability to dynamically
and rapidly adapt in response to changing environmental conditions. Dynamic
adaptability has been studied in other system areas as well and system
management through policies has crystallized itself as a very prominent
solution in system and network administration. However, these areas are often
concerned with very low-level technical aspects. Previous work on the APPEL
policy language has been aimed at dynamically adapting system behaviour to
satisfy end-user demands and - as part of STPOWLA - APPEL was used to adapt
workflow instances at runtime. In this paper we explore how the ideas of APPEL
and STPOWLA can be extended from workflows to the wider scope of Virtual
Organisations. We will use a Travel Booking VO as example.
