Hi Armin, you can get some similar things as that in MoI but the surface point editing toolset in MoI is not complete yet, there are things missing like being able to add in rows of points to a surface after it has already been created.

You can turn on surface points though, but if you object is made up of several trimmed surfaces joined together, you may need to use Edit/Separate first to break it into individual surfaces before their points will be enabled. See this FAQ for some details on that:
http://moi3d.com/wiki/FAQ#Q:_Why_does_show_points_work_for_some_objects_but_not_others.3F

The reason why that area is not fully refined yet in MoI is that for the most part I assume that if you are interested in modeling by manipulating surface points that you will likely be doing that already in a sub-d modeling system instead of in MoI, since those systems are very much focused on that kind of workflow. Instead of focusing on the same kinds of things initially in MoI, I wanted to actually focus on other kinds of things like booleans, 2D plan oriented stuff, things like that, so that MoI could work more as a complement to those kinds of tools and help out in different areas rather than trying to do the same stuff that was already available.

So to add in enough points to squish around you have to put in enough points in the surface when it is initially constructed. That means using several sections when doing a Loft, or also a good way to make a surface with a lot of interior control points in it is to set up 2 curves with plenty of points in them and use Extrude with the Set Path option, which makes a surface that inherits the structure of both curves directly. Rail revolve is also similar in this regard.
