Donating Time To Goodwill Projects?

jukal asks: "I am in the process of writing a proposal for co-operation between Openchallenge and UNITeS (United Nations Information Technology Service) which is 'creating a global volunteer programme aimed at bridging the digital divide between industrialized and developing countries'. Currently & traditionally contributing as a volunteer means relocating yourself to the developing country to take part as a project developer/manager/specialist. My proposal to UNITeS is, in short, will be that people could participate in such software projects via Openchallenge - while staying in their home country, on their spare-time and while keeping their jobs. The local team in the developing country would, after defining and creating requirements specifications post sub-projects as tasks to Openchallenge. All the contributions submitted to Openchallenge are published under an open source license. My question is: would you for example consider donating some hours to help a goodwill project - if you could do that from home. This is of interest to me, as I would like to be sure that the time we put into building co-operating with a big organization like UNITeS and others in the future. Is not wasted. There is this thread about 'Volunteer Work Abroad' - which is good reading related to the subject. But it did not quite provide me with the answer."
