The Share Skype blog has posted some information about the forthcoming Skype for Mac version that will finally include video calling, as well as a warning that there is a leaked version of the software making the rounds that is very buggy and will likely destroy your contact data. From the Skype blog:
Among all the excitement, we recently learned that there is an early development version of Skype for Mac with video floating around some warez sites. What you need to know about this version is that it is an internal unstable development version, and thus it is extremely buggy. It may and will destroy your contacts and other data. It is completely unsupported and if you experience problems due to using this version, you’re on your own.
Jaanus ends his post by whetting the appetites of Mac Skype users like myself with a screenshot of the Skype for Mac with Video client in action. Presumably not the buggy version.
