Mechanisms outlast products, and this word names a mechanism. Whatever the specific business, restricted access is a permanent and permanently valuable idea.
Exclusivity has two serious commercial lives. In luxury and membership it means scarcity and access. In law and commerce it means a binding arrangement: exclusive distribution, exclusive licensing, exclusive territory.
Both support a business. A members’ club, a private marketplace, a luxury platform or an invitation-only network on one side. A contracts and licensing resource, a distribution rights marketplace or a legal practice on the other.
The .net suits the platform and network readings particularly, and for a members-only operation the extension costs nothing at all, since people arrive by invitation rather than by typing a guess into a browser.
One long word, one spelling, no plural, no regional variant.
The name is available. Enquiries welcome.
