Parallels acquired by SWsoft

According to this article, Parallels was acquired 3 years ago by SWsoft:

The tectonics of virtualization are shifting. It turns out that Parallels is not such a little company after all. About three years ago it was quietly purchased by an enterprise-focused virtualization company called SWsoft, a fact that has never been publicly disclosed until now.

SWsoft is providing Plesk, HSPcomplete, PEM and Virtuozzo, which seems to be the only virtualization related technology. It will be interesting to see if SWsoft applies its expertise in Self Service, Accounting and Billing to the VM Management space.
