When considering the principles for eXtreme Programming, distributed eXtreme Programming, especially distributed pair programming, is a paradox predetermined to failure. However, global software development as well as the outsourcing of software development are integral parts of software projects. Hence, the support for distributed pair programming is still a challenging field for tool developers so that failure for distributed pair programming becomes less mandatory. In this paper, we analyse the social interaction in distributed pair programming and investigate how current technology supports this interaction. We present XPairtise, a plug-in for Eclipse that allows instant pair programming in distributed development teams. In addition, we report on experiences and findings when using XPairtise in a distributed software development setting.
