Multilingual (French, English...) applications - any hints?

I wonder whether somebody has been confronted with writing
multi-lingual applications using CL and CLIM. There are three
different kinds of strategies as far as I can see:

(1) Compile time conditionalization with #+ macros
(2) Load time switching using load-time-value (see example below)
(3) Run time switching by calling a function

Solution 2 is good enough for us. 3 may be less efficient an take more
space too. 

There are other issues involved, such as the question whether to put
strings in lookup tables (makes code smaller, but maybe not as readable)
or leave them in the code.

==> Could somebody do me the favor and tell:
   - whether the code below is the corrrect thing to do? 
   - whether there are smarter solutions for our kind of problem
   - give any other useful comment

  THANX A LOT  - Daniel
