Looking for information regarding the use of Skype in an Enterprise network

["Sam Evans" <wintrmte () gmail com>]

All,

I'm looking to find out how many large enterprise's have allowed the
use of Skype on their networks.  We are currently evaluating the use
of Skype as a method to make end to end customer calls and am
concerned with the security aspects of the product.

I'm curious what security policies companies have put into place
regarding the use of Skype.

Thanks,
Sam
