With Nimbusclient you can access files served by a Windows PC or Windows tablet in Dropbox style from a local folder using the Nimbus server software in a local area network (LAN). In this use case internet access is not necessary. Alternatively, when Nimbus server is not started but internet access is available, you can also use a synced cloud storage from the internet to serve content to Nimbus clients.
Additionally Nimbus also contains a collective drawingboard and a collective poll app which can be used when running in server mode.
The Nimbus server software is available under https://nimbus.codeplex.com/.
