This is exactly what we do in TextMate. There is an environment  
variable, individually defined for each “project”, called  
TM_LATEX_MASTER, that points to the master file, and a “simple” ruby  
script that goes through all the \include'd and \input'ed files, and  
picks out all the \label's out of there and prints them as a flat  
list, or optionally filters with respect to an initial segment of the  
word, for instance it could find all labels starting with “eqn:”.
The script can be found here:

LatexLabelCompletions.rb

We use some wrappers around it, but that's where the hard work is  
being done.	It currently uses some environment variables that have to  
do with with TextMate, but it can probably be modified for other  
purposes.

Not sure how easy it would be to incorporate it into TeXShop, if at  
all possible.
In terms of speed, it is not lightning fast, but it is reasonably  
quick to respond, definitely under a second, on my thesis which is 50  
pages and has 8 different included files. It definitely beats looking  
for the label in some other way.

It does not however deal with encoding issues at all, so I don't know  
if there are cases where it will break, or how to modify it to make  
it work. I've never had to deal with encoding issues on my files.
