LogMeIn Express offers simple screen-sharing solution
LogMeIn has been around for quite awhile now as a very useful free remote access tool for casual users, as well as a commercial remote access tool for corporations. They've now taken the obvious step of putting their technology to use in the form of a screen sharing application called LogMeIn Express.
The idea here is that you can quickly share your Windows computer's screen with up to 100 viewers by sending them a short 12-digit code and directing them to the LogMeIn Express website. Entering the code will then open a Flash-based page containing the contents of your computer's screen. As the presenter, you need to install a small piece of native Windows software, but the installation process is quick and painless, and offers 256-bit SSL encryption.
LogMeIn Express competes with more full-featured commercial screen sharing tools like GoToMeeting and WebEx, and though it's a much more simple implementation, it stacks up well. GoToMeeting is significantly faster than most competitors due to it being based on Citrix's Terminal Services technology, but LogMeIn Express competes well with WebEx. It doesn't currently include conference calling features which both of the commercial options do, but it does include an in-session chat module, and the ability to pass control of the host computer to one of the viewers.
LogMeIn Express is still in beta, but is free for both commercial and non-commercial use.
