Hey so Im sure you know that it was posted here but I found this article on Kotaku yesterday. It just mentions it but its a start.

Thanks! Next stop Steam hopefully. 
Thank you, thank you!
Panda3D makes its Steam debut as well, as far as I know!
This is very exciting!
I just bought the game yesterday. Everything works really well, it looks very professional, and the gameplay is highly original and fun. Congratulations!
I’d love to feature you somewhere on the Panda3D site. If you want to make a post to go on the Panda3D blog (assuming that it would go into detail about some of the technology behind the game, since the blog is aimed at Panda3D developers), let me know and I’d love to make that happen.
I played Signal Ops multiplayer with a friend yesterday and we had a lot of fun. The game is tricky to figure out at first (as with any novel game concept, I’ll bet) but once you get the hang of it, it’s a really fun game.
One thing that we noticed is that if two people happen to take control of the same screen (usually by accident), the movement of the associated character becomes locked-up and very jittery. Perhaps it might be possible to restrict this, so that only one person can take control of a screen at a time?
Also, when exiting or entering manholes, the camera occasionally glitches through the ground. It’s not a huge issue (mainly cosmetic), I just thought I’d point it out in case you guys weren’t aware of this.
Oh, and one small suggestion: it was not obvious which port to forward at first until I searched the web and found it in the Steam forums. It might be an idea to put this information in the network menu itself.
