If you'd like to see some unrelated but available and open-source code to generate rhyming metric verse: http://github.com/darius/languagetoys. Unlike the paper, this doesn't even try to preserve sense -- it just uses n-gram statistics.
OTOH, I don't want to give the good Googlers short shrift, and it is certainly welcome to consider the meter (and maybe rhyme) of generated text.
machine translation!
autumn rhymes abound
