Streaming from ReadyNAS without password

Access won't be an issue since you can setup either anonymous access to shares on a network or user accounts (with u/p) and automatically save the u/p on the local machine used. It would depned on the nature of how your team works (shared computers, or dedicated comptuers, remote profiles, etc.)...this would be for video transfers, but may not be the best way to do it. Streaming content may be a better way, but that depends on the software used. Not sure what you meant by access via URL (weblink?), since if the software uses a URL to access videos, then you'd probalby need a webserver setup for video streaming videos from your NAS (either a seperate server or directly from your NAS), eg Emby, Kodi, Plex, Mezzmo, Media Portal, etc..

The bigger issues would be, how to manage multiple users IF editing the same video? If the video is just for viewing, then this would not be an issue and there are many solutions to stream to multiple users, again it depends on the software you use to view videos.

Also getting the right NAS (and fast enough network speed) to cater for simultaneous video viewing - this would depend on the quality and size of the videos (4k - 8k, etc.), weather or not they'll be streamed or transfered.
