Why not specify that every node / user has a custom path , in the  
user / node table.

During initialisation it just means we have to do 2 more small  
lookups to see if the url has been aliased.
Creating links we have to make sure to use the $node->path or $user- 
 >path property.

This would cut down on a number of queries for aliases as you almost  
always have the node object / user object
when you are busy linking to it

We'd still need the alias table for anything that aren't these  
primary objects though.

You can still provide additional aliases with the alias table, but  
these won't be used as
outgoing links over the node/object path.
