When I said the update is easy, I mean I put new CD that I received
from Jeppesen and the install program does the work; I do not need to
remove old paper charts and insert new ones. If I am on the road and
cannot receive CD that Jeppesen mailed to my home, I can access Jepp's
website and update my portable through the web.

I think your reply means if I go to a part of the world that is not in
my subscribed area, can I download that area. I actually called Jepp
on that. My subscrition only covered "southwest" and if I need to
travel to Seattle, I can buy a JeppView "TripKit" which is not on their
website, but available by calling customer service. The "TripKit"
works the same way paper TripKit works, but it is for JeppView. I have
not tried it yet, but during JeppView installation, install program
asked me if I have additional access code for coverage areas. I would
think when I called for JeppView TripKit, I paid with my credit card
and customer service would issue me an additional, one time only access
code for the area I am going to. Anyone who has experience please
share your experience of using JeppView Tripkit.

As for sharing computer in a club, I asked about Jepp's muti-user
license. The customer service person told me that additional muti-user
license save on the one-time $100 setup fee, and can activate on
additonal 4 computers. In my case, I paid $100 setup plus $195 a year
for southwest coverage. If my friend want to share my setup, we pay
additonal $195 a year, and between us, we can activate upto 8
computers. Please note that I use "activate" then "install" because
the program as is could be installed to as many PC as you want, but if
you do not activate that installation, the program stops working after
30 days.

I have not asked if the 8 computers could be used by more than 2 pilots
with more than 2 aircrafts. But it would be great if 4 people could
share 2 muti-user licenses with each person having 2 program
activations. That would be more affordable than paper charts
subscritions.
