Although this sounds like an excellent proposition, I wonder about the load that using Skype will take on an enterprise level data network, especially one that, presumably, was built to only handle PC related traffic.

While it seems that Skype *may* have built some sort of technology into the enterprsie client to alleviate this concern via their "enterprise network compatibilty", I know of 50-100 person companies that use Skype, who struggle with issues related to to voice/video calling on their PC data network.

If the load can not be adequetely handled by the enterprise network, it is fairly certain that latency, jitter, and packet loss will occur resulting in a less than favorable calling experience, and more than likely poor results from the Skype for enterprise program.
