That argument is on pretty shaky ground. You might, in that case, start charging extra for FURLs, AJAX skins, or any other progression in the software... as far as I'm concerned, my license entitles me to use IPB and it's features in all future versions, forever... You're moving the goal posts in order to sheppard legacy customers into your newer pricing bracket...
... and yes, I do pay my annual support fee already.
I also think it vital to get links in RSS feeds FURLed... I figure if I keep mentioning this thread, someone will write me a patch...
