Super expensive! For just over the first class price, you can fly return to Australia, in the same amount of time! As it's not cheap, I wonder - does it have fast wifi? This and traveling with large amounts of luggage (probably not allowed anyway) is about the only reason I can imagine to use it.

If you are interested in pedantic histories of such things, check out en.wikipedia.org/wiki/TeX

Basically, two spaces was a hack on monospace typewriters to create a more visually appealing document, prior to the advent of automated typesetting, 38 years ago.

TeX was the first system to really create accessible automated typesetting, setting the standard for computer typesetting for decades, and still broadly in use (in later iterations) particularly in academic circles. It was initially programmed by a single guy, Donald Knuth, who is an absolute genius as well as an interesting fellow.

TeX used to produce DVI (device independent) files - referring to the capacity of these files to be translated in to commands for different types of printing hardware - and then PS (postscript), which was the vector format graphics language used by many printers that Adobe's PDF format is derived from.

"Since version 3, TeX has used an idiosyncratic version numbering system, where updates have been indicated by adding an extra digit at the end of the decimal, so that the version number asymptotically approaches π. This is a reflection of the fact that TeX is now very stable, and only minor updates are anticipated."

Pedantry is awesome. If you are interested in modern printing history and the transition to phototypesetting and digital typesetting, two of the better museums are in Lyon (France) and Prague (Czech Republic).

biotaxa.org/Phytotaxa/article/view/phytotaxa.284.3.3 is an academic article 'Species of Psilocybe (Hymenogastraceae) from Yunnan, southwest China' (just came out - dated 16 November 2016) but USD$17 pricetag.

At least the following species exist here (source was a Chinese academic pictorial mushroom textbook):

psilocybe argentipes
psilocybe coprophila
psilocybe cubensis
psilocybe cyanescens
psilocybe fasciata
psilocybe merdaria
psilocybe venenata

You can do it - but just because they are both running doesn't mean they are both in use. In general, they are not designed to be used together.

Roughly speaking there are three ways to route outbound internet traffic, by proxy server (generally browsers only, though there are some other applications and VPNs with proxy support), by application (not supported on all platforms) and the standard method with TCP/IP routing.

The standard method only allows one VPN to route your traffic. The proxy methods may allow multiple VPNs to be in concurrent use, however you are basically still going to be using a maximum of one VPN per open application (that supports proxying).

Finally, application-based routing may be possible on some platforms, with the same limitation (one VPN per given moment per application).

Overall, it's generally pointless unless you have a super specific need.

@cloudtrapezer Public DNS servers are nothing to do with VPN providers. You are the naive one here.
