In Finland there has recently been quite a lot of public discussion about open data in daily news papers (http://bit.ly/sWb6ZA). The government has also agreed that all official data should be made public. However, the government has not stated anything about the means to make such data public.
What do you see as the main obstacles to open data?
For example, I would structure it as "in order to use the data for any purpose, internal or external, the open infrastructure must be there". In other words, everyone uses the same mechanism so that it can't be bolted on as an afterthought that may or may not work or be maintained.
