Firefox can be customized through the chrome about:config menu. Some ppl may not find it very user friendly but you can set a lot of the features you may miss in the options/preferences menu. Some features you don't get at all, true. But hey, it's free!
Just my two cents...
you seem to be forgetting that these companies have to make some money to keep offering those services. I don't think some coins offered voluntarily by tourists at the exit would make up for their expenses.
any login/credit-card-payment etc would complicate the system and scare away those concerned about their personal data being gathered by some company. to me, paying cash at the entrance (hirepoint they call it) and not worrying about the cellphones' batteries doesn't seem that bad at all
there was a presentation/workshop for Wireless Sensor Networks (WSN) about two weeks ago in my university. WSN is the same network (protocol) family of ZigBee. Actually, Ziggy is only one of many still-under-development WSN protocols. Even if zigbee is far ahead in the development roadmap than the protocols developed in our department, it is proprietary and all of these still have way to go.
as for the purposes of WSN in general and zigbee just think about wheather/traffic/air polution monitoring through a network of sensors which elaborate data locally. these networks provide a wireless infrastructure for gathering, merging, aggregating data that is stored on senor nodes and who are relative to the observed process.
this may still be rather theoretic, but the low power requirements and operating in an environment with limited resources differentiates WSNs from other network systems and there is a lot of research going on in this field.
i hope i gave you some more info on what Zigbee and WSNs in general are (or should be;) about. i explained mostly the point of view of that workshop, naturaly. personally i think that WSN and personal computer networks are not the same thing, at least wsn don't try to replace pc networks since the scarse bwdth of wsn could never offer you video/audio streaming or online gaming;)
