I wouldn't be happy with anything short of independence for South Ossetia and Abkhazia. The chances this agreement leaves for it are very slim.
You are mistaking both of them for actual states as we understand them in the West. They are nothing more than puppet states, governed by Russia. The vast majority of the government officials in Abkhazia and South Ossetia are Russians, usually Putin's former buddies from the KGB. They use the two countries for their mafia operations as well as keeping Georgian sovereignty in check. Abkhazia's supposed "democracy" is a farce: the Russians ensure only the candidates they support win. South Ossetia doesn't even bother. The Russians have supplied Abkhazians and Ossetians with Russian citizenship even though many haven't ever stepped foot in Russia. Russia has even passed laws that treat the two provinces as part of Russia, a point emphasized by the military takeover of Abkhazia a few months ago.
The governments of Abkhazia and South Ossetia have no popular support and it is likely that they don't view independence from Georgia as an important objective (the South Ossetian referendum was quite clearly heavily rigged). Just look at Adjara, the third Russian puppet state in Georgia, which was retaken by Georgia in 2004 fairly easily and successfully.
This is not about Abkhazia or South Ossetia. Neither of them are real sates. Its about Russia and Georgia, and the Abkhazians and Ossetians are being used by the Russians to threaten and attack Georgia.
