Subject Statusable

Whilst porting the apps, I noted that there is no consitency as to what 
is printed to sys.out at startup of Phoenix.  It is clear that some sort 
of message is needed because newbies, will be underwhelmed if nothing is 
printed.  I believe in the "five second test".  In use, if it is not 
apparent in the first five seconds that some tool is excellent, the 
potential user will dislike the tool.

If we had..........

interface Statusable {
  void setStatusManager(StatusManager sm);

interface StatusManager {
  void setStatus(String status);

At startup, the blocks launched could, if they wanted, keep the system 
advised on their status.  After Phoenix has invoked the last lifecycle 
method during a startup it may choose to dump a table of statii to the 
console.  Thus we have a standard output for each block.

We also, in some future management console, have a refreshable table for 
blocks.  The idea is that this info supplements the concrete "started" & 
"initialized" types, with stuff like "listening on port 1234, 321 
transactions performed"

Thoughts?  I'm also thinking this is not just useful for Phoenix....
