* well, you could just name your subpart ###LOOP_NEWS### ...
* you can format data with TS
* let's not talk about the code of tt_news. That's a different stoy, 
tt_news has grown over time and we know that it needs a 3.0 rewrite to 
keep it maintainable at all.

this is possible, at least in tt_news it's so flexible that you can have 
hundreds of alternative/alternating

Why do you limit yourself?
The core at the moment says it's working on PHP4 AND on PHP5, but itself 
uses PHP4 only. I'd always use PHP5 if I can.
No one is going to limit you. Especially as it's an extension not the core.
