We've written before about Dimdim, an outstanding open source web conferencing application which may be of special interest right now to businesses looking to save on travel for meetings and the like. Today, Dimdim has announced an upgrade that offers synchronized co-browsing, better scalability and enhanced performance. Version 4.5 now lets you start a Dimdim "room" and send anyone the room's URL, after which users on the other end can see what you see as you go to various web addresses, view data and videos, and share online data. This is another good move that differentiates Dimdim from a very crowded field of conferencing applications.
Dimdim has been quick to add features not found in many popular, free online meeting applications. For example, you can have up to 20 people in a free Dimdim meeting, but only 10 in most other applications, such as the free version of Yugma. Dimdim also allows you to record online meetings without the fees that most of the freeware applications charge. It should be noted that the new Pro version 4.5 of Dimdim does cost $99 per year for some extra features, but you get the co-browsing features in the Free version as well.
A lot of the utility of the SynchroLive features in Dimdim will depend on performance, especially if meeting participants are going to share videos and the like. From the announcement of the new version: "For example, a meeting host can view a YouTube video and every attendee will immediately see this video play in their browser. Simultaneously attendees can chat, talk, and see the presenter live using just their browser."
That's where I could see some latency issues pop up, but the company claims that performance is excellent. WebEx, which is widely used for online meetings and for sharing things like video content, has conquered a lot of performance issues by building out its own network of servers nationwide. That's hard to compete with, but Dimdim is focused on high-performance competition, as seen in their "WebEx is Dead" screenshot below.
Dimdim has also released "Liberty," which is the newest open source community edition of its application, under a GPL3 license. And, in a move that I think is shrewd, the company is pursuing integration with other open source applications, including:
This type of integration makes sense for Dimdim. Moodle, for example has hundreds of thousands of dedicated users of its open source e-learning software. Online conferencing is an ideal adjunct to such applications, and these types of mashups of multiple open source applications can help people avoid substantial costs for proprietary equivalents.Â
