I just tested using TeXLive 2012, and in fact it doesn't work with xdvi,
but it works just fine with evince 3.8.2.  That is, I disable
`TeX-PDF-mode', compile a doc to DVI, then

  C-c C-c View RET TeX-evince-sync-view RET

fires up evince with the dvi file.

Then Ctrl-click in the DVI makes point move to that location, and

  C-c C-c View RET TeX-evince-sync-view RET

centers that line in Evince again.

As said, evince does.

I don't think we should try encoding viewer capabilities.  IMO, it's
easy enough to set the correct method for whatever combination of output
and viewer people are using.

No, synctex should work also with plain latex.

Since it works for me, yes. :-)
