TeamViewer goes cross-platform, now available for download on Linux
Some of the more recent additions -- like per-application screen sharing via TeamViewer's toolbar button -- haven't made it into the Linux version yet, but things administrators need most are there. Remote (both hosting and control), file transfer, chat (both text and voice), and session recording all work nicely. Partner Lists are also available on Linux, making remote connections to your saved hosts a cinch.
Right now, TeamViewer for Linux is beta software. Like other TV betas I've tested on Windows and Mac, however, the Linux version is very usable and every bit as solid as most of the stable release software I run.
TeamViewer has provided .deb and .rpm builds for both 32 and 64-bit Linux distros, and a .tar.gz download is also available. Head over to the Linux download page to try it out!
