It sounds like OP has found that six different ways to connect to the Internet is the minimum that is viable for him, and that meeting that is important enough to justify spending a large portion of his limited budget (both financially and in terms of space in/on his vehicle).
If one fork does the job, one fork is enough. If five way to connect aren’t enough, then maybe six will be enough :)
I disagree. The highly specialized monitoring equipment and dual high gains antennas and the plethora of other bits and pieces are NOT required to run a "a meeting" or a "netflix stream". A phone with a sim card usually suffice. All this frivolous spending points out that this is a hobby. Nothing wrong with having hobbies, of course, but the spending is not compatible with the definition of minimalism.
A minimalist online meeting is an IRC connection over 3G.
You're underestimating how terrible internet connectivity is in rural Australia. A lot of places will only have 1 provider that offers service, if any at all.
