I'd really appriciate any help I can get, so feel free to give me some feedback on what
I'm planning to implement:

1.  Controller. By including a new file descriptor in the set that is examined in dispatch() I
     should be able to, from another process, write commands on the fifo belonging to that fd.
     The controller will be called when such a command is received and should do the
     appropriate actions:

2.  Address renewal. Try to renew the current leases by calling state_init().

3.  Subnet selection option. I haven't started thinking about this implementation yet so please 
     share your ideas :-)

4.  Release specified address. The client have to be able to release one of it's old addresses.
     If I can get hold of the client_lease corresponding to the given IP-address, would it
     require some modifications to the make_release() and send_release() functions, or could 
     I use something like the client_reinit (state) you sent me last week?

I do hope you have time to look this through, Ted.

TIA
