BTW: Even these setups can be fixed. One way to extend the available
port ranges is to allocate more than one IP address; either through the
use of multiple NICs, or through address aliasing. You can set up the
services to listen on one interface, while setting up your routing
tables to ensure that any outgoing connections to your NFS servers go
through through a different interface.

You could also use virtualised machines to host the services, etc...
