I do not know about the time share golf club, but I did recently read about a the Inverness Club in Toledo, OH, that was allowing people who lived a certain distance away to get memberships at significantly reduced rates. Sounds pretty similar to what you are thinking, Patrick.
Here's the blurb from Chris Millard's Golf Digest article:
Inverness now offers one of the best nonresident deals in all of golf. Historically, Inverness has offered a handful of nonresident memberships. In recent years, however, the club has found opportunity in what it refers to as "regional" and "national" memberships. The initiation fee for a regional member (who must live 45 to 100 miles from the club) is $9,000. Annual dues are $4,200, and there is no food minimum. National members (100-plus miles from the club) pay an initiation fee of $6,500 and annual dues of $3,480. Each classification has full use of the club and the ability to entertain seven guests daily.
