The 'what' is the problem.  If our sales person want to
demo a product that connects on 6 different ports to
places that aren't known until the first connection
is established, will it work?

I didn't design the product, but I've had to help make
it work in places that don't use a default gateway. 
It's not pretty.

The reason there are other ways is that none of them
are perfect.   There's nothing wrong with understanding
the flaws and tradeoffs of each.

Generally I don't want applications to use a proxy
unless I know they are going to download the same big
files as other systems.  Otherwise it slows things down
slightly and has no benefit.

That's a reasonable approach, but takes an extra step and
unless the same programs are installed everywhere the
1st system may not have all the others need.

I'm not demanding solutions, but if people don't consider
the problems there won't ever be any solutions.

It's a one-line command.  How does making it a script
help?  You have to spend the time to create the script
and then it takes just as long to type it's name as
the command itself - or recall it from history.
