You can be a permanent resident of multiple countries, but e.g. Canada will require you to have lived in Canada for 730 days in the last 5 years to keep your status of a permanent citizen.
To be registered as permanently living somewhere, you have to pay the local taxes, and prove that you have a residence there, as well as other proofs probably.
Seems like an interesting step to take.

Ukraine will prefer to fuse with the European Union as if it wasn't another way of giving up its independence. The Russian Federation can give freedoms, like the e.u. can and perhaps even more since there's less inside competition.
And historically it'd make sense. Of course Europe wants more territories, everyone does, but they don't want to include Russia because they fear that they won't control it, it's stupid Europe should have tried what it could to include Russia in the e.u. obviously, now the Russian Federation is on a path to become a distinct center once again.

I haven't read it, but if you want to know more here's a recent conference on this subject : http://en.kremlin.ru/events/president/news/76450
Here's an excerpt :

Question : What is the current stage of integration planned for 2024–2026 ?
Vladimir Putin : First, all 28 programmes that we planned have been implemented 100 percent.
Second, we have fulfilled more than 26 percent of what we planned for 2024–2026 so far.
