40 iPads running SyncPad at once

by Steven Sande Apr 7th 2011 at 3:00PM

SyncPad (US$9.99) is touted in the App Store as "the ultimate whiteboard for remote and local collaboration." That description really doesn't do justice to what SyncPad is designed for, which is sharing an iPad screen with one or many other users.

SyncPad developer Davide Di Cillo of 39 Inc. received a video (see next page) from one of his enterprise clients who put the app to the test. In the video, 40 iPads are shown doing the iOS equivalent of synchronized swimming. Every gesture and action on a host iPad shows up on the other iPads immediately. While there is a tiny lag on some of the more dramatic changes (i.e., going back to a full-screen slide), a demo of drawing on a whiteboard shows no lag at all on any of the devices, which are all using the same Wi-Fi network.

This app could have amazing uses in business, education and entertainment. Enjoy the video.

Does this allow me to run a Keynote Presentation on iPads, controlled from 1 master iPad?

The variable delay between ipads would seem to indicate that the application doesn't use multicast which might be fine except a large deployment like this is probably going to wreck any other applications on the WLAN while it's happening -- plus it probably couldn't handle operating in something like a school setting when you'd potentially have a few hundred users on it.

That being said, it's really not very surprising that it doesn't use multicast -- it's really really difficult to set up multicast properly in a wireless network, particularly a larger one and there are only a few vendors that really get it right. The return on the application developer supporting multicast is probably not there.

Does ARD do multicast in this type of application? I know there is no iPad viewer; maybe this is why...

This is the iPad killer app… You don't need another iPad to view just a browser and the presenters SyncPad URL. If you do have an iPad you can use the free SyncPad viewer or with the full SyncPad version join in on the presentation… Like I said KILLER APP!!!

It's just Apple Remote Desktop for iPads. Actually ARD would be better as it can initiated and controlled by the main server.

You read the article? You did see that it mentioned the customer being an enterprise customer, correct?

I don't think the person got the iPads just to play with them...most likely testing them for giving presentations and whatnot.

This would work out so well in classrooms. Though that would require that every student have a iPad, not to mention be focused and running that app.

I think a few of them would be on Facebook.

At least no one's fingers would be smashed by the professor slamming the cover over their hands.
