Hello Maurice!

OH!  Ok, if dupe-checking takes into consideration the "address"  
part along with the "serialno" part, then uniqueness is pretty  
good as it stands.

I thought the concern was that some dupe-check implementations  
only use the "serialno" part.

True. There could very well be a collision created on the same  
system given enough time.

Good point. That guarantees uniqueness. You win.

BUT.. you must agree that the likely hood of two rando numbers  
colliding given that any of the 8 chars in the serialno part can  
be [a-z][A-Z][0-9] at 62^8, is pretty unlikely.

Even a serial number based on an incremental 8 char string with  
[a-z][A-Z][0-9] could work too.

I'm amazed how long the services of TinyURL have relied on 8- 
char uniqueness.  As far as I can tell they only use the  
lowercase letters + the numbers:

 ..the service as been operating for a l-o-n-g time.


And, now that we've totally bored the vast number of ASIAN_LINK  
listeners, we should probably move to something less technical.
