Someone has managed to get Steam working well on Wheezy, and quite safely, by "sandboxing" the libc6 2.15 and other Ubuntu libraries. A little bit of of searching on these forums would have turned it up, since we answer the question every other day.
https://github.com/GhostSquad57/Steam-I ... for-WheezyThe correct way to get Netflix on Chrome is for Google to shape up and provide proper packages, but they may not put a priority on Wheezy since there are no officially backported libnss3 packages. I did manage to rebuild the Ubuntu libc6 2.15 against Wheezy libraries, but that ended up breaking some other important libraries such as policykit--but I did that dangerous test install in a virtual machine with the previous state preserved in a snapshot, so reverting to that state took a few seconds.
We do have Netflix-desktop ported over to the Wheezy-based MEPIS 12 and MX 14 community repositories. Though the articles deride the older method as complicated, it's actually very easy to get going on MX, and I imagine adding the correct repositories to Wheezy would end up making it also easy.
