[tor-talk] Awareness for identity correlation through circuit sharing is almost zero.

Multiple socks ports are in stable, we'll make the transition to multi-
Socks in TorBOX in the next days, certainly before before 0.2.3.x
becomes stable. Once the update hits the repository this will be
automatically available in TorBOX.
However: "Tor Browser should set SOCKS username for a request based on referer"
Until that gets fixed the whole feature is pretty pointless.
You worry about apt-get reducing anonymity to pseudonymous
but TBB is just as affected and compared to those implications
apt-get is absolutely negligible. We discussed this at:

How so? People can customize and install their own packages in
Tails too. By default neither TorBOX nor tails has a unique "application
fingerprint" and TorBOX doesn't automatically phone anywhere.
In fact due to the VM depended design TorBOX will always be less
leaky by design than a live cd (it can't leak hardware serials).

DNSPort allows us to fail "openly" (just wrt to the circuit correlation - it's
all still torified) for non-critical/one-off stuff. (I count apt-get to the latter
but this can be easily changed)

I'm interested in your other reasons. This one is none we couldn't solve,
and we will. But we can only do so once 0.2.3 becomes stable.
There is nothing we can do right now about it, or is there?
Also, is there a (technical) reason a single TransPort couldn't be safe?
There's nothing SOCKS specific about IsolateStreamsByPort
