Beeweeb Server Enterprise Edition 1.5
Beeweeb Server Enterprise Edition for Linux allows non-FTP Web site administration and publishing, easy remote access, file-sharing, and content streaming over any IP network.
Using its own protocol, it gives users direct read-and-write access to any kind of file without having to download and upload it back.
This is completely modular and scaleable both vertically (on a simultaneous user basis) and horizontally, in order to share traffic among different servers.
You need an evaluation key, see homepage for details.
