Adobe just launched a new Acrobat.com website, a complete set of web-based communication, collaboration, and productivity tools. From Adobe: ConnectNow.
ConnectNow is a great way to share ideas, discuss details, and complete work together — all online. Reduce travel costs, save time, and increase productivity with a web conferencing solution that is easy to access and simple to use.
A good synopsis of the platform can be found here.
The free service only allows for three participants and a host, but the Pro Version allows for up to 1,500 participants.
A service like this doesn't even need to replace a physical conference, it can compliment, even enhance, the program by turning distance and technology into a bonus. Especially for program committees and other administrative work, tools like this could certainly help reduce the cost of travel and materials.
A test drive is in order.
