There's a way to name spaces.   In the space "service configuration" 
file, import net.jini.lookup.entry.Name, then add this line in the 
outrigger config:
initialLookupAttributes=new Entry[]{new Name("InsertSpaceNameHere")};

A space can hold many objects (though it may be limited to 
Integer.MAX_VALUE or a similar value practically).   Basically, you're 
probably going to run into problems with heap size long before you have 
a problem with the number of objects.   If your space runs out of 
memory, you can always allocate more memory to space via java command 
line the next time you run.

I dunno, but you can always write your own wrapper for space operations.

Well... I don't know of any great online resource, no.   But googling 
problems you run into usually works fairly well.   Or asking the mailing 
list when that fails.
