Hello Wikiwizards,
I have developed an application that reads the RCstream, performs a filter/augmentation operation[1] and then rebroadcasts the filtered RCstream.
The problem I am running into on Tools-Labs is that when I submit to the grid, the rebroadcasting of the filtered websocket stream is happening on a different server with each submission to the grid (i.e. task@tools-exec-##.eqiad.wmflabs). So how can I have submit the rebroadcast job to the grid and have the rebroadcasted websocket be accessed by a static address, so that external people can read it? What is the best strategy?
Some solutions I can think of: *Should I make an instance for this? *Write out to the filesystem and rebroadcast from a webserver? *Dynamically bind incoming requests to the jobs-grid?
[1]the operation is to look at the content of all changes and filter only those that involve addition or deletion of specific wikitext template parameters.
Make a great day, Max Klein ‽ http://notconfusing.com/

I can think of several strategies; part of the difficulty comes from the fact that what you're doing is not intended to be easy: allowing arbitrary connections without proxying breaks a number of Labs rules about getting IP addresses from end users.
The very best way to do this is through a web interface, if it is at all possible, because that allows you to coopt the proxy infrastructure already in place.
Another solution is to broadcast your augmented stream over an IRC channel as well; this has the secondary advantage of making it easy to write clients (there are numerous IRC frameworks available for pretty much every language) and is easy to debug by inspecting the stream with an interactive client.

Marc, another message to this list this morning, is about a rebroadcast of the RCstream with a json->xml format transform, so it seems like there is a desire to transform and make available the RCstream.
Thanks for all your advice.
