Nope, you will only get a 404 if the elements have never existed  
before. If it has been deleted you will get a visible=false. Take this  
example:
http://openstreetmap.org/api/0.6/nodes?nodes=15,18

The maximum number you can request at one time is limited by the  
length of the GET request, there are no limits set our code, so you  
may need to bulk it into groups like the gps points call.

We could change the call to silently drop the 404, and always return  
all elements that it could find, with only the elements that could not  
be found being missing from the list. If no requested ids could be  
found, then and osm document with no nodes, ways and relations would  
be returned.
