I take it that doing a "M-x visit-tag-table" for each TAGS file is not
an option, and neither is to create another TAGS file which would just
include the real TAGS files (using the --include option to `etags'),
right?

In that case, I'd suggest to customize the value of `tags-table-list'
to include the names of all the directories where you have your TAGS
files.  This could be done with, e.g., `shell-command-to-string' that
runs the command "find . -type d", followed by processing the
resulting string into a list.

Yet another solution is to stop having TAGS file in each subdirectory
of your project (why is that a good idea, anyway?), and instead have
only one ;-)
