One workaround would be to have two (vastly different) 1918 prefixes
and giving people the possibility to switch (so, 2 SSID's, 2 prefixes,
say 192.168.224.0/20 and 10.210.32.0/20). Chances that someone will
conflict with both, are small.

For better or worse, we will need to learn how to deal with this - 
denying these issues doesn't fix the fact that these situations will
happen, without the escape of availability of public IPv4 addresses,
in the near future.

And, of course, if nobody puts pressure on the VPN-sellers, these issues
will stick around for *years*.
