But client-side tunnelling relies on having an IPv4 address too, so it
doesn't solve depletion.
Estimates I've seen so far from IPv6 day suggest that although traffic was
up, V6 accounted for between 0.02% and 0.3% of total traffic. Of that, 90%
was tunnelled (i.e. only 10% native). So basically: (1) there is no
signficiant IPv6 Internet today, and (2) if you want to join what there is,
you do indeed probably have to tunnel.
That doesn't mean that installing a tunnel client is a good idea for anyone
except network specialists who know what they're doing.
If random end-users start installing this stuff without understanding it,
then (a) they are probably opening up security holes into their network, and
(b) they may impede a later smooth rollout of native v6.
