this is possible only in current development version, you need to add an
event_route and based on the target ip or local socket ip you can decide
to apply topoh or not:

Current development branch will be released as v5.1 in few weeks.

I will have to look at the code, not remembering by heart what can
happen in case of a spiral... The overall goal was to hide the details 
of caller and callee from each other...
