A proposal made by one of Spain's political parties during the recent presidential elections shows that "community" suffixes are going mainstream.
Andalusia's Capital, Seville
"Coalicion Andalucista" (the Andalucian coalition) is a group of various regional Andalucía political parties. During Spain's March 2008 presidential elections, the coalition put the creation of a .AND Internet suffix amongst its manifesto proposals.
Although there's no concrete proposal to ICANN as yet, the coalition's .AND idea does show the importance regional TLDs are beginning to have for specific communities.
Other community TLD proposals have already come to light, such as Brittany's .BZH. And of course one such TLD, .CAT, has already gained ICANN's approval and been launched. There are currently about 28,000 .CAT domains.
