By now I’m sure you heard of the Skype-powered Facebook video calling that was announced yesterday, if not you can read more here. Essentially you install a small application and it upgrades your regular old Facebook chat to include a few new options, video calling being one of those.

Recently self pro-claimed geek, Jeff Rose, blogged about something he found while sifting through the code of the recent Facebook download file, which is necessary to run the new video calling feature. His findings are quite interesting, as the code supports two projects: facebook.peep (which is the video calling feature), and something un-announced… facebook.vibes.

Rose elaborated on what he thought this could be:

“At some point in the future they seem to be prepared to download another app though, called Facebook Vibes. I searched around to see what this is all about, and it seems that this is an unannounced feature that has yet to be released. The vibes app connects with a music download dialog in the page though, so I’m guessing that with this release we are seeing the seeds for Facebook’s upcoming music offering.”

Could this be the name of the rumored partnership between Facebook and Spotify? It’s interesting timing, as it was just announced that Spotify was coming to the U.S on Wednesday.

What do you think Facebook Vibes is? Let us know in the comments.
