I have updated the simple Cloud list server. (available in the download section)

New stuff in version v1.4:

• added a UDP HELLO message for clients. This helps XBSlink nodes to check if the incoming port is open or closed.
• the Cloud list server checks if a joining XBSlink node is reachable or not.
• nodes with open ports are preferred to announce to joining clients.
• table layout changed (delete old XBSlink_clouds.sqlite3 file on update!)
