New legal entity for social enterprise in UK

Just learned about a really interesting new development in UK regulation of social enterprises. Community interest companies are brand new, have only been around for 6-8 months . They are like for profit companies in that there can be shareholders, dividends (capped), but they are like non profits in that if they are sold they have to be sold to another community interest company. Need to do a lot more research, but if we had something like this in the US, it would be perfect for GlobalGiving.
