Hi again, so I spent some time looking into the problem and wrote a short summary at http://twkozlowski.net/russian-wikipedia-under-threat-again/ (<shameless promotion mode="off" />) -- if anyone cares about what's happening outside of the US, that is.
As described in the summary, there are plans for a massive strike on the Russian Internet (Runet) on August 1, with the bill being described as the Russian equivalent of SOPA. It also looks to me like there is some public opposition against the bill (a petition to the President of Russia already has over 130,000 signatures with just 100,000 being required), so the situation is developing quite interestingly.
