I did understand that you wanted the communication pattern without having to depend on dune-grid. This is exactly what we wanted in dune-fem, too. To this end, we use a single grid-based communication to build up the communication pattern (the way we need it). All later communications then bypass dune-grid.

For example, if you want to know the InteriorBorder_InteriorBorder communication pattern for vertex Dofs, you can do the following: Create a data handle that communicates data only on vertices. In gather, you always write the rank into the buffer. When scattering the data, you know from which ranks you receive a specific vertex, so you can store a link between the index and the other rank. This gives you the receive pattern. In this example, the send pattern is identical to the receive pattern. This pattern can now be used to communicate vectors storing vertex data without using dune-grid.
