Not sure what you mean by recursively, but if you just mean 
doing the equivalent of query-replace-regexp on mulitple
files, take a look at etags:

1) First make a 'TAGS' file to include the files you want (shell)

   $ etags `find . -name "*.blah.*.foo"`

   This makes a TAGS file in the current directory

2) In emacs, do M-x tags-query-replace.  It will query 
   for from-expression, to-expression, then the location
   of the TAGS file.

etags is extremely powerful for language specific
stuff, but works just fine for iterating over
a set of files.
