Quoting from the Kidaro official announcement:

Kidaro, provider of virtual desktop computing for the enterprise without boundaries, has announced the Kidaro Managed Workspace™ for extending fully operable, managed, secured and easy-to-use work environments for enterprise users anywhere. Kidaro Managed Workspace encapsulates selected corporate resources and tools — OS, applications, IT/IS management software and remote access clients — into a centrally controlled, protected and isolated workspace that can be deployed to any end–user.
…
Kidaro’s unique set of technologies go one step beyond any other virtualization platform for enterprise desktops. Leveraging standard, vendor-independent machine virtualization technologies (e.g. VMware Player, VMware Workstation, Microsoft Virtual PC, Microsoft Vista), Kidaro brings the essential elements required to successfully deploy a complete virtualization solution for enterprise end–users:

• Centralized Management
  Kidaro’s powerful, unified management console streamlines the way IT administrators can create, deploy and update virtual machines, monitor active users, and generate audit trails and reports
• Optimized Delivery
  Patent-pending Trim Transfer technology dramatically accelerates deployment and reduces the network bandwidth needed to transport a virtual machine by an average 90%, allowing fast delivery via any remote network connection
• Seamlessness, Transparent Operation
  Kidaro Managed Workspace is the only solution that does not change the user experience when a virtual machine is introduced. The workspace integrates between the local and the virtualized desktops to create a familiar look-and-feel
• Data protection
  Kidaro Managed Workspace enables policy-based control over any network connection, file transfer, printing, copy-paste or device access, enforcing corporate policies and regulatory compliance

At first sight Kidaro Managed Workspace seems a Sentillion vThere competitior.
