There's already a proposal floating around on the dev list to introduce a new address type, P2SH^2, which would allow the relevant data fields currently being used to stuff the info discussed in the article to become hashes. This would have the effect that if you wanted to stuff arbitrary data, you'd be limited to finding hash collisions. See the thread here: http://sourceforge.net/mailarchive/message.php?msg_id=307056...
I've been lurking on the bitcoin-dev list for a while to observe how they handle issues just like this. I'm confident that these problems will be transient.
