Something to consider for us low level travelers who are mug targets. You could offer medical insurance for a speedy recovery or traveller's cheques to protect your money. Right now there's a few ways to protect your cash but it requires a trusted 2nd party playing at the same time. You know you're picking up 30 million in merchandise and you get mugged even before you get out of the airport.
For the medical, I suggest Blue Cross for a fee based on your level can provide better health care than the usual hospital at the travel sites. This would offer a place to recover quickly and stay safe until a player is ready to leave. Sucks to be stuck waiting for a revive or try timing an online session for your hospital eviction.
Travelers Cheques cost 1.25 times their value, provide 1/2 value to muggers and if you have to make 3 or more claims week, Insurance can refuse you due to your high claim incidents.
This could also roll off an Insurance industry.
