i think only a percentage of the openspace sims is actually offending (meaning: using enough resources to lag other openspace sims on the same server)

i propose a plan which:

• saves the homes
• punishes the clubs
• doesn't increase costs for LL
• doesn't increase prices for (innocent) users
• does not change the original idea behind openspace sims (meaning: light use only)
• needs very little development effort

here goes: measure the resource usage of openspace sims, possibly averaged over a timeframe (a week?), divide the statistic in a number of classes, for example:

90-100th percentile: worst offenders
70-90th percentile: moderate offenders
0-70th percentile: not offenders

warn offenders that if they don't fix their sim, they will be moved to a server with only other sims in the same class. then they punish each other, and non-offenders can live peacefully without lag.
after having moved, they can move back on request, and paying a fee, if they fixed the problem (closed that club they were running, for example)

combine this with publicly showing in the client that a particular region is openspace sim and that it lags because its using too much resources.

also, offer a "half sim" - 2 on a core, $150 per month, and suggest offending openspace sims to upgrade to one.
