In this paper, we propose a fully decentralized system for software package management and distribution. Comparing to existing repository-dependent approaches, our system addresses more attention on the massively growing User-Generated software content and the emerging Internet of Things. We first illustrate some statistical results and reveal the major properties of package distribution. Then we revisit the current structure of software packages and formally define our system model. After this, several candidate application-level protocols for efficient package retrieval and advertisement are investigated. At last, some open issues concerning the package certification and the heterogeneity of participants are highlighted for future research.
