Here is part of a press release on OLPC's work in Haiti
We are doing what we can for the 60 schools that we have been working with in Haiti – primarily planning for the spring after the first phase of rebuilding is underway. We will be sending a group of OLPCorps volunteers to Haiti later this year, and are organizing a used XO drive to recover XOs in the US that can be refurbished and sent to Haiti. Luckily, our Haitian team (technical and in the government) was not hurt in the earthquake, and they are planning to help displaced students get back to school as quickly as possible.If you are interested in helping use the above link which has the links you will need.
Meanwhile, around the US, people (including our own Adam Holt and Tim Falconer) have been gathering in CrisisCamps to brainstorm ways to better use collaborative technology to help groups on the ground. If you are technically-minded, there is a real demand for programmers and interface designers to help some of these projects thrive.
