Some great posts there everyone, thanks for them all, I will try and answer in one go rather than seperately.
The Shieling Project is hugely inspiring and the crofting principle is highly practical, but I expect the "basic" look in the video, especially on a overcast and damp day will put a lot of people off and get them thinking "muddy cold commune" as much as community.
Tinkers Bubble in Somerset is another great project with similar ideas and concepts, but one look at that site and its slow pace of development might not appeal to so many people either. Another very nice group of people though.

The Findhorn project is at the complete opposite end of the scale, but equally has its merits and goes to show what can be done with plenty of funding behind you. It has developed over the years way beyond everyone's expectations from what I understand.

On a more personal note and close to our hearts is "Blatusa" in central Croatia. Again it is somewhat basic looking due to limited funds, but it hits the mark in terms of its manageable size and the groups commitment to building community spirit is very genuine, perhaps in part as its residents comprise a wide range of family units and age groups, who came from all over Europe and South Africa.

We are in our 50's now and of an age where we have some capital behind us and can afford to buy a reasonable property and live [frugally] off our pensions, savings and whatever work and barter we put our minds too. We want enough private space around us to grow a decent amount of our own fruit and veg and not have to listen to our neighbours music or rows.
We dont want to live under canvas or in a caravan again while building our home, we've done that enough times already. We want proper walls and a roof, solid floors, power sockets, running water and heating without trudging through 12" deep mud in wellies for 6 months of the year. All we want is to move somewhere suitable, into a proper house, with neighbours at a decent arms length away, that have similar views to coping with life as we do. No power trips. No councils or committees. Just a bit of common sense and respect along side like minded people. Trust takes time to develop however and would hopefully build over time.
It's not the first time we have done something like this, we started something similar from scratch 20 years ago and ended up with a [loose] community of about 30 friends, mates and acquaintances, the closet couple lived a few hundred yds away, the furthest being 20 a mins drive. We didn't see each other everyday but someone was always planning a get together of some sort at least on a monthly basis. No one lived in anyone's pocket and your personal privacy was whatever you chose it to be. But we all knew that if there was a problem, serious or otherwise, we could call on any number of people who would come and help us without question or delay. We were sad to leave that experience behind and realise now just how much we miss it, especially as we get older and [less?] wiser. As in any community those who were fortunate enough to have an income or pension etc and could afford to pay for any work they needed doing did so, but would spend the money with other members of our [loose] group first wherever possible. I also found bartering was a wonderful thing to learn and accept.
Everyone has their own ideas and preconceptions of what lies ahead, ours may be more pessimistic than some, but more realistic than others. If our visions for the future turn out to be correct, then we will be part of a [loose] community that can handle some of the problems we face collectively, as friends who are equally committed and prepared as everyone else. If the future turns out to be rosy with no societal, economic or other major problems, we will still just be living alongside good people in a lovely area of the country somewhere.
Think that covers everything?.
