I recently discovered this as I had a need for something else but I thought it might be nice to check the status of remote and local frontends.
I wrote a script that displays local and remote frontends status in conky and I would like to share it with you. I am just learning about scripting and this is my first attempt at variables i mostly just put stuff in that i could be typed type from shell with no variables or error correction so i learned a bit preparing this.
The instructions on how to use are in the comments of the file and this link should let you know about mythtv telnet and how to enable it.

I think it is pretty subtle considering how much I had to write in order to enable a few lines in conky. Anyway, this was fun for me i hope people try it and let me know how it goes post back if you need any help i would be glad to help if you have any problems setting it up.
