I've wanted some Internet service that I can access on the road from different places in the USA, that means that I usually have some level of connectivity, and at least in many metropolitan areas lets me have something near broadband speeds with low latency - without having to go to a public place.
Is there anything like this yet? As far as I can tell, things either aren't much rolled out yet, or they're aimed at particular types of connection rather than someone just with a laptop wanting general Internet usage - ssh, ftp, sip/h323, etc. - and with a globally routable IP, even if it's dynamically-allocated, instead of an RFC1918 address.
So, I haven't been blown away yet by what I've seen on offer so far, based on what I can tell of what cellphone providers, etc. have been doing. Am I missing something? It's sure been hard to tell exactly what's on offer.
Basically, is it possible for people who travel from city to city a lot to get proper broadband Internet connectivity (as if they brought their cable modem along or whatever) without having to go to particular hotel chains or Starbucks or whatever to find themselves on 802.11g behind NAT, or limiting what kind of Internet access they have? (e.g., some packages seem designed with the expectation you just download web pages or whatever.) Is there just not the demand?
If (as I suspect) not, who or what should I be looking at if I want to notice when it appears? Is there any effort in this direction?
