Hello Brendan, this is fantastic, welcome to the list! > We have the Ubuntu packages running fine, but it is evident that there are > changes that should be made to Sugar when its not being used on the OLPC. > Some of the challenges for deploying Sugar on desktops in a school > environment are different than using it on standalone OLPCs, which need to be > overcome for Sugar to take a major foothold independent of the OLPC.

As you might know there are several efforts going on to use Sugar outside OLPC and some of the problems you mention below are common to these other projects too. I think Bernardo is going to setup an upstream trac instance next week. It would be cool if you could start opening tickets there. We can use them as a way to discuss the issues your run into and to figure out solutions that can be taken upstream and benefit the community as whole. > The technical challenges we see are mostly problems integrating sugar into a > thin client architecture, and into the networks of schools.

I've been wondering about how to better allow to customize the "shutdown" options. One possibility would be to use Gconf schemas. Control panel pages are extensions in git master, so they can be more easily added or removed. > On larger installations, schools will want sugar to integrate with there > existing file and print servers, as well as some centralized administration > of the sugar interface.

The next generation of the Journal will have much better POSIX compatibility, which should help this use case. Even with the current implementation though, I think it's possible to display the journal contents through a web server, that people could browse from a Windows/Linux computer. (Tomeu, in cc, should have more details about this.) > It would be interesting to see if we could launch sugar activities without > running the entire sugar interface. That's one of my medium term goals about compatibility with standard desktop. I'm going to talk about it at xocamp. Contributions would surely help to speed up the process :) > Also, local media attached to thin client may pose a challenge, as the normal > ways to search for and mount media are not available. Can you elaborate on this? I'm not sure to understand what's the use case exactly. > Another important aspect of larger sugar deployments would be the ability of > admins to customize the user interface.

I think GConf and sabayon has been successfully used for this kind of customization, for the GNOME desktop. We might want to go down that way as well. > One of the most interesting aspects of sugar is its collaboration features, > but this too poses some difficulties.

Do you mean that as an hard limit or a soft one (i.e. students would see their class "by default" but would also be allowed to see anyone else on the jabber server if they want to)? In other words, are you worrying about scalability or about privacy? > These are some of the issues were thinking about.

In git master, we have switched to GConf to store the preferences (there is still a profile class but just for compatibility). Does that work well enough for you? Or which problems do you think you will run into? > We are very excited about the possibilities that sugar provides.

Please keep posting us about any question or idea you come up with it. Either through the mailing list, the irc channel or the weekly meetings!
