All valid download links of the old version of ACOnet FileSender and of the previous test system continue to work until their respective expiry date. However, existing vouchers (function "Invite Guest") of the old version have expired with the upgrade and need to be reissued on the new system.

Since 2013, ACOnet is engaged in the area of distributed performances / telematic music in real-time over high performance data networks. After three internationally successful multisite performances under the title net:art - near in the distance, the next step was to create the comprehensive website - a platform that promotes interactive live streaming for e-learning and productions of the performing arts. The website offers an introduction to relevant technologies, documentations (videos, photos, info) of previous shows, concepts for new collaborations and links to international cooperation partners.
