Since I first wrote about it in September, I’ve been eagerly awaiting the free, open-source DimDim, a direct competitor to the arrogant old commercial apps Webex and GoToMeeting, as well as upstarts like Vyew and Webhuddle. I finally got a demo of this important new app, which goes into public beta this week. We have exclusive invitations to the closed beta right now if you want to jump in ahead of everyone… read to the end of the story for access.

When Josh and I first fired up the product last week, we both walked away confused. It looked like it did a lot, but simple things slowed us down. I could send him a stream from my Webcam, for example, but he couldn’t send me his. The Powerpoint sharing feature showed a smaller-than-expected image on Josh’s machine. And where the heck was the End Conference button? There are UI bits of DimDim everywhere, like the dashboard of an over-optioned Citroen.

Mostly the interface is scattered all over the place, so this tiny wizard is a large help.

But over the weekend, while not in so much of a rush, I had some time to explore the product a bit more and came away impressed with its abilities and the technology itself. I found the End button, too.

Setting up a meeting in DimDim is very simple. You can kick off a meeting immediately of schedule it for later (including recurring meetings). I didn’t find a way to load up a future meeting with resources (PowerPoints, PDFs, and Web URLs) though. It’s easy enough to bring these items into a meeting once it’s in progress, but doing the prep ahead of time would make things look better to the participants.

The product lets you do on the internet slideshows using PowerPoints and PDFs. You can annotate as you go and let users mark up, too. You can also work on a shared, multi-page whiteboard. Or share your screen, which is useful for demos.

There are several ways to interaction with your viewers. You can send them Webcam video and audio (or make it two-way if you like), chat with all attendees, or send private instant messages to individuals. I didn’t see polling, quiz, or hand-raise features, though. I also expected an integrated way to set up a conference bridge over the phone, but didn’t find that option.

One massive benefit of this product is that viewers of a presentation don’t have to download or install any apps, plug-ins, ActiveX controls, or Java giblets. That is sure to please viewers like me who don’t like junking up their system just so they have the ability to get pitched.

The conference host can control what people see as well as what they can say (click to enlarge).

However, at the moment the user interface itself is rather slow to respond to inputs. Also, the company doesn’t guarantee speed nor high-quality audio or video transmission on this free service. If you pay for the pro version ($99 a year per presenter) or the enterprise edition (which you can install on your own servers), you can control the quality of service and get support help from DimDim, but I do worry that free users won’t be inclined to throw money at the product if they don’t have a great experience to begin with.

So the product review summary is this: DimDim is a very strong Web conferencing tool. And you can’t beat the price. It’s definitely good enough to make one reconsider renewing a Webex contract.

But wait, there’s more. As I stated at the top of this story, DimDim is open source. That means that it could become not just a Web meeting app, but a platform for real-time communications. For example, according to CEO DD Gangully, the DimDim developer community is working on modules to add widgets to the service, support Open Social, improve chat, add presence, integrate better with email, support documents (Google Docs?), and work on mobile devices. The open and free nature of the product means that other developers could patch their ideas into it in ways you’d never see happening on Webex. That’s the potential, anyway. We’ll see if the product gets enough traction to attract a vibrant developer community.

I advocate trying DimDim. To get onboard before the app goes into open beta on April 10, go here. There are only 1000 invites set aside for Webware readers, so don’t dawdle.
