query-replace across buffers in Emacs can be done by doing an etags on all
files you wanna replace.  A "TAGS" file will be created.  Get into Emacs
and do M-x tags-query-replace.  Specify the TAGS file you just created and
viola!, you can query-replace across buffers!  This is a hack taught to me by
my workmate.  The really _great_ thing about query-replace in Emacs is that
you can replace multiline strings!  You do this by putting the string you wanna
replace into a kill buffer and when doing the query-replace, yanking the
buffer.  Only the last line will be shown, but the query-replace will work
correctly.  It's totally awesome because writing the same thing in Perl is
a horendous pain.

I do not know of a way to run macros across buffers, unfortunately.
