e-touch activation and marriage to computer host

[fb28]

A few questions from a newbie - please bear with me...

First, is an internet connection required to register e-touch,
or can it be done off-line?

I think that I read that the commercial (coin-op) version was
locked into the host, and if there was either a failure, upgrade
or other reason to relocate the s/w, that I would need the new
machines' ID (I guess public key) and they would issue a new
registration number/key for the new machine. Have I got that correct?
IOW, if I installed e-touch on a "new" "coin-op" machine, and used
the same registration key - it wouldn't run? Would it default to demo?

Same question if I had another coin-op copy on a development machine,
and it failed - if I relocated/re-installed that e-touch s/w on a new
machine would that require another/new license file?

Does the registration process (as far as relocating/restoring the
S/W on another machine) work the same for the standard vs coin-op?
IOW, need new licenses - each "married" the hardware by some public
key? Same procedure for either version: send email with ID numbers
that came with that copy's download, and I would get a unique
license file for that copy?

Does the standard version have some time-limited coin-op functionality
in order to test/emulate an operational/revenue system? IOW, would
I need two commercial licenses to have a development system identical
(except for the hardware environment) for full emulation?

"Life member" My understanding is that for "lifetime" credit,
it's the cost of the option (i.e. full, commercial) x 2 - so, $70
for the full, if you get the commercial version - will you get
lifetime support, or is it $500 (x2) for lifetime commercial?

What is "lifetime support". While the "future" is a long ways
away, what if the company decides to discontinue the product,
or maybe the owner decides to retire - any number of things...
Is there a plan for a backup to issue new/replacement licenses?
Especially for the commercial (coin-op) version, which by then
will still be relied upon as a revenue source and not "go dark".

e-touch seems to be one of the best-rated s/w solutions for
a private-owned box, but it's not just the investment of the
extra $$ for the commercial version - one needs to consider
the long-term availability (and oh yes, most likely replacing
failed hardware from time to time).
