Aloha Martin,

Here is the basic idea in pseudo python.  

#begin_src python :results output latex
 ... weird latex code
s = ''' 	\\put(-2,-50){
 		\\parbox{8cm}{
 			\\tiny{%s - %s - %s}\\\\ \\\\
 			\\normalsize
 			\\textbf{%s}\\\\
 			street\\\\
 			\\textbf{%s}
 			\\vspace{2mm}\\\\
 		}
 	}''' % (mycompany, mystree, mycountry, company, country)
print s
 ... weird latex code
#end_src python

hth,
Tom
