Proposal: Have traffic limits based on number of parcels owned by a given owner or group within a region. For example: two concurrent visitors (residents not owning the land) per parcel. The visitor allocation is applied to the whole of joined land, just like primitive data.
A frequent (at least annoying enough to seem frequent) occurrence is "server hogging" - almost always unintentional, but it happens. Basically, a land owner builds an attraction that pulls in a lot of traffic, saturating the server resource, while paying for just a small fraction of the server allocation, e.g. one or two parcels. Thus a minority land holder becomes the sole user of a whole server, with other land owners (AKA server leases) locked out, getting the infamous "server is full" message. In effect, via their monthly land use fees, these locked out owners are paying overhead for the high traffic attraction's business.
Worse, this can easily happen to long time land owners, when a new person buys a parcel or two, creates a high traffic site, and kills accessibility to the other content by the other owners.
This proposal is intended to mediate the conflict. Typically, server lock out occurs when the traffic reaches forty residents. As a server supports 128 parcels, this lock out means that the server can handle only roughly only 1/3 residents per parcel! If a parcel allocation of two visitors is imposed, an owner would need to hold 10/128 of a region before having the capability of saturating the server with traffic. As this is just a mid tier ownership (5120 m2), it is hardly a burden on those who wish to host high traffic areas.
