Number two is clearly the easiest. :-)
I'd look at the third route first, and if it seems too hard, then I'd back
up to the second approach.

In addition to the xpdf "pdftops" program, I'd also look at output from
ghostscript's "pdf2ps" program. I expect they would be similar, but both
have been mentioned as alternatives to acroread.
