It appears that the only current offerings of IGH with coaster brakes, from Sturmey Archer/Sunrace are the S-RC3 three speed and the 2SC two speed hub.
If you include cable actuated drum brake options, there are three, four and five speed IGH models available.
If the concern is to limit the use of cables, the coaster brake arrangement will only eliminate the braking cable- one is still stuck with the shifting cable .
Shimano makes two coaster brake Nexus models, the three speed SG-3C41 and a seven speed version; the SG-C3001-7C-DX.
The old Sturmey Archer coaster brake models included the notoriously unreliable TCW models. Avoid them them like the plague! This series was superseded by the SC3 series. These newer hubs, are rumored, as well,to be more fragile than the non coaster brake models or the drum brake models.
