Ah, OK, sorry I didn't read all the discussion. So I guess that if you keep that in a global variable, it won't work if your Django app is running in many processes. (Besides, global variables are rarely a good idea.)
If I understand the problem correctly, what I would do would probably be to touch a file whenever I make a change and examine the file modification date each time—if it's more recent than last time I checked, the data has been modified. Another option is to use the cache. For example, use memcached and store some data in there. IIRC the cache is shared among all instances of Django.
