I know that a common problem with Android tablets is that they lack multi-user support. I wonder if there isn't already a solution that allows me to select the user on boot by linking/moving/changing the data partition.
There are boot managers that allow the selection of the (custom) ROM to be loaded, just like Windows/Linux dual-boot. Are there any Apps that allows me to select the data partition/user on boot? Or let me switch the user data on-the-fly without rebooting?
you can use SwitchMe if you have root, which I believe does all you ask
Dont know exactly if you are satisfied with this, but in the near future VmWare will release one version for Android.
This adds a little bit of multi user support, because you can start another android system like any other apps.

Sorry, but this is my best answer:
You could have a system where you mount an sdcard partiton as data etc for the other user, unfortunately, there is no project in development for this THAT I KNOW OF.
However, this would work, unfortunately, you would need to reboot, so it isn't really what you wanted.
Titanium Backup has a 'multi user data profiles' feature that can be used to have a per app multi user like functionality: It has some restrictions like 'doesnt work with apps that have services', etc.
