For that matter... I'm working for a consulting firm right now with a job that is up to 100% travel. Some of my coworkers are "homeless", in that they don't have any fixed abode: travel and hotel rooms for 5-6 nights a week can be expensed to the client, so they just go to the beach, go skiing, or visit family on the weekend. Of course, this is hardly the traditional state of deprivation you hear associated with "homelessness". I mention it not just to add a data point and widen the spectrum of "homeless", but also to point out that it's still a bit of a challenge to maintain formal relationships with institutions like banks, insurance companies, and the government when you don't have a permanent address -- even for someone with plentiful resources, in the email era, with readily available Internet. Perhaps this will continue to improve in years to come, and the (traditionally deprived) homeless will also benefit.
