HereSphere doesn't support the Keon or DLNA yet, but probably will before the end of the year.
However, to get scripts to work, you'll probably need to use SMB, which is Window's default file sharing method. From my understanding, DLNA is really only used to stream videos. Other types of files won't work.
If you have a PC with bluetooth capabilities, you could use HereSphere's timestamp server with ScriptPlayer, a PC application that can control the keon while synchronizing with video playback in HereSphere.
