From RDA Solutions:
Remote Desktop Anywhere allows you to access your home or work computers over the Internet, even if they're behind your home router or corporate firewall. Remote Desktop Anywhere is the only remote access solution that uses Windows' built-in remote desktop component to provide a responsive remote access experience. This product is for workers who need to access their office computer from home or on the road, or need to access their home computer from the office. Although there are several remote access solutions available, Remote Desktop Anywhere is the only one focused on providing the most responsive experience possible. Anyone who has waited 3 seconds for a mouse click response can attest to the importance of speed in a remote access solution. On its own, Microsoft's Remote Desktop client cannot access PCs behind office firewalls or home DSL or cable modems. RDA Solutions has solved this problem with Remote Desktop Anywhere. Together they provide a superior experience in terms of speed and stability. The remote desktop protocol has been exclusively optimized for Windows. Users and IT staff are already familiar with the Remote Desktop client, so the learning curve is minimal. With Remote Desktop Anywhere, users can control an Internet-connected remote PC from any Windows, Mac, or Linux computer.
