- incompatible licence
- incompatible architecture
- huge resource consumption, especially when several Nmap processes are
launched in parallel and all allocated dozens of MB of private memory
to store the same information.
- try to find detailed information where Nessus only needs open ports. 
The consequence of the last point is that Nmap becomes sluggish in some
vicious situations. nessus_tcp_scanner just grabs the open ports and
does not care if the remaining ports are closed, filtered, firewalled,
or even NATed to the moon with a RTT > 2.4 s.

OK but that was not the topic. 
Feeding Nessus with Nmap results may make sense, but running Nmap
*from* Nessus just does not.
