Provided that the workarounds mentioned in this page are applied: everything, from installing the launcher to logging in (maybe with another workaround, see below) to installing and launching games through it.
What does not
After launching with the Wine default configuration, the connection to the Uplay servers may stall at "initialization". At least, it does for me. Hence the "Gold" rating instead of "Platinum" (see the workaround below).
After configuring Wine to run "upc.exe" as a Windows Vista exe (and letting everything else run as default Windows 7), I can connect to the Uplay servers flawlessly. Workaround inspired by the comments to the Bug 41652.
