Hello Monks!
Long time lurker here...

I'd like to toss this idea out and see if anyone has done this before. I googled, I searched the Monastery and CPAN to no avail.
In short: is there a module for PJLink? If so, where is it? Has anyone written anything like this? Does anyone have ideas for one?

Longer explanation: I work for a theater company that uses a digital projector to present Operas in one of our cinemas. We also use it for rentals and some film engagements where digital source is only available.
To control various cinema equipment (the sound processor and lighting dimmer mainly) I built a cheap hardware interface and a computer out of recycled parts. This all works great but the content server is third party and only communicates via PJLink.

Further, the digital projector can be controlled by PJLink.
I'm using Perl to write the software to control all the functions based on where we are in the program. i.e. program start, lights go down, sound switches in, etc.
So writing instructions to the projector over the LAN using PJLink is one of these steps.

I'm thinking I could further extend functionality by writing a daemon that pretends to be a projector to the opera server and then interprets PJLink commands from the server to control all the equipment, projector included.
Basically I'm looking for someone in my shoes or somewhere thereabouts to bounce ideas off of. Any insights, ideas, suggestions, etc. are welcome.

Thanks in advance!
