I will definitely be keeping a close eye on this. Personally the 2 hour timers are perfect, as if someone wants to deny me my toy, I can at least 'drive conflict' instead of bending over under the current system. Being able to bottleneck fights into a zone when i can stave off the initial result, rather than getting all my stuff locked down while I am asleep, is a good direction for CCP to go IMO.
These Citadels are very limited for my purposes, but are a step in the right direction in terms of allowing us to provide services to everyone we choose. We can effectively freeport facwar systems for either party, provide all kinds of exotic 'truck stop' services in stationless pipe systems in high and low sec, and much more. Out of the box thinking and reasonable docking fees could make this an earner for those with the ability to hold on to a distributed network.
CCP is showing some rare insight into leaving the meta purposefully open ended here, and I am pretty excited to follow this to its logical conclusion. When we know more, I might be interested in talking with some fellow station enthusiasts about ideas for services and monetisation.
