I guess there was only two other things you missed that I would add - both 
are related. These are

* efficient way to search a particular node type. Different node types will 
require different strategies to search and index and thus we will need to be 
able to create particular search controls/scanners for different node types. 
The nodesets return by these search controls may not even be fully resolved 
until you actually try to access elements from the nodelist. Does that make 
* caching of indexing information. Ideally you don't want to load the index 
for a zip over and over again. Nor do you want to keep index information for 
all VFS nodes in memory. We need an efficient caching mechanism for this sort 
of stuff.
