do you have any known websites that use dy namic content stuffing?

Have you seen anything at all in any G . Patents that might suggest penalties for php includes ? personally I cant see how this is anything other than providing a better service to the web visitor. Delivering relevent content.

do you know if Hiding text in collapsable DIV tags would be considered “adverse” to seo?

Some of my websites I have hidden further relevent text paqragraphs on my web page, simply because i dont want to clutter my page with too much wordy text, and distract from the visitor experience.

Im not actually sure if it gets atributed to SEO by the big G ? If It did one could do lots of ‘grey’hat stuff with that, but like any of these things G is on to it. So its best to keep it for enhancing user experience, and if it does contribute to SEO , thats by chance benificial.
