This week’s tech buzzword is Jabber.  Jabber is another addition to the Cisco Software Family.  What? You thought Cisco was a hardware business? Think again.

When Cisco bought Jabber, the open source instant messaging app known for interoperability,  they didn’t just buy a corporate IM — they bought another key component for their vision of the future. A future where collaboration is built into the network rather than on top of it.

That’s right. While everyone’s been buzzing for months about Google and Microsoft and Yahoo,  Cisco’s been quietly rebuilding the bones of your network so you can get more value out of the infrastructure you already have in place.  Some people call the concept unified communications. Some people call it ubiquitous computing. It might just be simpler to call it Cisco Software.

Rumor has it that Cisco plans to include Jabber as part of its WebEx collaboration platform.  Makes sense. It fits in quite nicely with their telepresence technology too. The Jabber announcement comes less than a month after Cisco announced plans to buy PostPath, a Linux-based email and calendaring outfit, for $215 million.

Here’s my next prediction:  CISCO will buy Twitter.
