Hi Tassilo,

you are right, it does not work with orgstruct-mode, because that sets  
local variables like in Org-mode for the duration of the command.

I think the best solution in this case, where you want to do mainly
visibility cycling in an arbitrary mode is using outline-minor-mode and
bind org-cycle to some convenient command.

There is a FAQ which describes a setup for this,

"Can I get the visibility-cycling features in outline-mode and outline- 
minor-mode?"
