There have been serious protests in the separatist republic of Abkhazia (de jure belonging to Georgia but de facto under Russian control). This time the demonstrations are against the Kremlin-backed government. Unlike South Ossetians, who have been agitating for union with Russia, I get the impression Abkhazians would really like to be independent from both Georgia and Russia.
It will be interesting to see if this is just a flash in the pan. If not, I wonder how Putin will handle it.
