We have created the e-learning application called Whiteboard, designed for long-distance on-line teaching. The application is used by various servers and, can for example, mediate the teaching of languages, where the teacher does not have to live in the same location as the student. Both can use video transmission through a web camera, transfer files, or write and draw on a shared board. The whole lecture can be recorded and later played back for repetition. Adobe Flash Media Server was used for the server.
