TeamViewer has released a new version of its cross-platform desktop-sharing software, TeamViewer V4. The headlining feature in V4 is browser-based access, allowing remote connections via a web browser. The browser connection will work across platforms, allowing PCs and Macs to share desktops with one another. The remote control utilizes Flash components instead of ActiveX, reducing the risk of unwanted executables and browser plug-ins activating. The browser feature also brings another new component in the form of shared presentations. Up to 10 users can log into a browser session and share screens, though this is a premium license feature.

Version 4 adds Partner lists, permitting trusted people or remote computers to be saved to a list, where they can be accessed with a single click. The list also tracks the status of each account, and can be opened from a remote system as well.

TeamViewer offers remote administration features and file transfers, and can be run without being installed. It works across firewalls, and uses 256-bit AES encryption. V4 is free for non-commercial use; business licenses cost $250 for a six-month period or $700 for lifetime use, and the premium version costs $1,400 with a lifetime service license.
