Today the web conferencing service, Mikogo, announced the release of Mikogo Skype Extra, creating a complete free web conferencing solution. The service requires a single download, that automatically installs upon download and now allows Skype users to collaborate via 4 different communication mediums: voice, chat, video, and now screen sharing.

Mikogo Co-founder, Mark Zondler:

Regardless of whether it’s for business or private purposes, Skype users now have the complete Web conferencing package completely free. Free screen sharing combined seamlessly with Skype’s free calls, free chat, and free video, really give the Mikogo Skype Extra users the perfect means of Web collaboration.

While not as robust and comprehensive as other corporate web conferencing services, Mikogo Skye Extra is a complete solution for small web conferences, and best of all, it’s free. Mikogo free screen sharing, was created by BeamYourScreen, to allow users to host professional online meetings allowing them to collaborate easily with colleagues, clients, suppliers and friends and family.

The addition of Mikogo’s user friendly, free screen sharing services will make online communication more convenient and affordable. By eleminating travel costs and saving time for all parties involved, Mikogo could change the way people and businesses worldwide correspond and collaborate over the internet.

BeamYourScreen is a new web-based app for the Apple iPhone that lets users engage in desktop/screen sharing and Web conferences using the popular handheld device. iPhone owners can enter their session ID through the Safari web browser and view the host’s desktop in real-time. Anything loaded by the host such as websites, PDF files and Office documents can be shared. Up to 20 guests are supported.

The service operates through the web, so normal iPhone controls still apply, such as zoom and tilting between portrait and landscape modes. Users cannot however make a iPhone call and run the HTML viewer at the same time, as the current 2.5G iPhone does not support simultaneous voice/data connections. A separate phone is needed for receive audio conferencing.

With the immanent release of the 3G iPhone this Summer, and recently rumored native videoconferencing capabilities, BeamYourScreen is likely to be only the beginning of the mobile webconferencing and videoconferencing revolution.
