The Handhelds.org infrastructure is designed to facilitate the development of Open Source software on handheld and wearable computers. They have been most noted for allowing PDA users everywhere to run Linux on many PDA models. The OSL hosts an infrastructure cluster for Handhelds.org (web, cvs, ftp, nfs, and more) which has a sister cluster at MIT. We also host a development cluster of iPaq handheld PDA's and skiff computers.
