are these dwf files?  I recall having to change every url in one of
these files, and it actually wasn't too hard.  I believe what I did
was unzip the dwf's (they're just zip format, containing a bunch of
files).  Again, it's been a while, but one of these files in the dwf
zip was a  xml file that had the urls in it.  I ran the file through a
perl script to change the url's as needed.  I think there was a trick
to updating the dwf file though.  I couldn't just zip the files up
into a new file and then rename it to .dwf, I had to update the
original dwf because I think it had some non-standard header bytes at
the beginning of the dwf file.  I recall the updating of the original
dwf to be tricky/troublesome.

I should remember this better, but this is all I've got.  Your dwf's
might not be the same file format version as mine was.
