Users of e-collaboration systems are often enforced to have special hardware and/or software to support communication, data processing and storage. Obtaining such infrastructures will make them face financial efforts, but sometimes, depending on many factors, costly solutions could be not acceptable. On the other hand, use of mobile systems in working process and trends like Bring Your Own Device (BYOD) give people more flexible ways to interact with each other. In this paper we describe an innovative system for real-time interaction based on regular mobile devices, which is designated to improve usage of current e-collaboration solutions and enhance mobility. The main importance and advantage of mobile-based implementation with ad-hoc wireless networks is hardware-attachment elimination, user's flexibility and inexpensiveness of system. Proposed system works without being connected to the internet, a cloud service, a server or even a WiFi router. The core of the system is a low latency mobile server which handles all requests and performs necessary computing fast. This ensures a high degree of usability, mobility, reliability and safety.
