Abhishek Singh from OLE Nepal published his long and excellent XS wishlist, generating a long discussion on the server-devel mailing list (1, 2) and other discussion online. He discusses some specific use cases for current and requested-future features, including:
Porting XS to new version of Fedora
Support for more architectures
Web content filtering
Shared Journal Backup
A platform for socializing
Some specific packages needed for the above.
On the list, Martin comments on the package requests, Mokurai weighs in, and Sridhar points out what OLPC-AU has been doing with their XS builds.
The WFP has been developing some lovely materials to support their work with OLPC in Nepal. In a recent animation short, Nim Doma Sherpa (the youngest woman to climb Mt. Everest) and an acrobatic yak (who seems to have been working with her for some time) snowboard down a mountain to deliver XOs to a school of children. Priceless.
