IOSA.it Open Archaeology

My question to the forum community is related to the need to back to the earth.
I was very well impressioned by Grosseto's workshop, but, in the same time, a bit concerned about.
I tried to explain my thought, but I'm not sure I was cristall clear. I try again.
I asked about costs. An archaeologist must spend some 5 months per year on a digging site (never forget that no digging no applied computer science), 3 months on potsherds and is always late for reports. An arcaheologist cannot spend 12 months per year facing a flat monitor, searching for new solutions. So...If I leave the old path for the new one...how much does it cost to me in terms of self-learning, data portability (we used to have tons of data)? And, above all, where to turn myself? I felt that computer scientists do agree in terms of generalities (parachutists), but they offer different solutions (truffle hunters).
I turned all my GIS bases into Grass for linux. But at the moment just one person of my research group can manage the new "age". So the transition is not free at all. And I ask to you all to discuss more about how to allow a soft and low cost transition to OS. If you really want to have more appeal, I think this is the right way.

Happydigger is a program which can be used for cataloging archaeological finds. It is intended both for semi-professional use and by amateurs (e.g. metal detector users) who want to keep track of their finds. Data is stored in a database with extensive find and findspot details. If images are available, they will be displayed together with the find information.

The objective of the Free Open Source IDAMS (OpenIDAMS) project is to produce, keep up-to-date and disseminate a free open source software package for data management, exploration and archiving, with report generation facilities, by transforming IDAMS into an evolving, inter-related set of end-user and developer services. The UNESCO Secretariat is the promoter, co-ordinator and supervisor of the project.
The complete description is on the UNESCO website.
