i got the know how.
allready developed some programs like the requested one.
will use phantomjs to realise these scripts.
1 script per site (nike, eastbay, footlocker)
and maybe one "overlaying" script, i would choose to realise it using perl, which reads the tweets and call the site-scripts if requested.
feel free to contact me if you have questions.
kind regards,
michael adamcik
