Rick,

have used it when we were testing the .csv processing of FreeSWITCH (like a couple of years back). Should be still actual AFAIK, otherwise let me know if you run into any kind of issues.
Regarding maintaining some kind of real-time, you can call the script from cron every minute or so and I think that is the closest real-time you can get since until FreeSWITCH will start writing a new file (rotate old one), you cannot process it externally since you will get concurrency on write/read. In CGRateS you will process it instantly based on inotify events but the CDR file needs to be first released by FreeSWITCH.
If you want closer to real-time, maybe mod_json_cdr is a better option for you?

Thanks Dan - did you use this in conjunction with a file watcher, presumably, to maintain some kind of realtime? 

You say you ?used to? use it, does that mean it?s FS version thing? What I can?t work out is that there are older cdrs in the directory that have 770 permissions, yet I haven?t updated FS or anything like that, so I can?t work out why they would now be writing out with 700 perms!?
