Apart from the normal group of object, I don't know any other way of doing
this in Ipe. I agree that this would be a nice feature, however it would
probably make the whole user interface much more complicated.

A feature that would not complicate  the interface but still take care
of your problem would be two modes of  the move command:
1. Ordinary move, that moves only the objects selected.
2. "constrained" move working only for objects consisting of a closed
   path. When moving the path, also all points of lines (including those
   not selected) that can be found within or on the path are moved.
This approach is used in programs like tgif.
(call this a feature request)
