Re: Fixed layout titles and real problems today

I can't resist chiming in here to say that if you haven't checked out 
Ken's CircularFLO software, you really should. IMO it is amazing, and 
more people should know about it. (Since you may know that I'm a 
consultant, I should say here that I have absolutely NO commercial 
connection to Ken or CircularFLO.) His expertise in this area is why I 
encouraged him to join the EPUB WG. And since I've got his attention now 
;) I will encourage him to take the lead on a Task Force on this in the 
WG or maybe even better the CG. That's where things like this get 
incubated and I think Ken could get that work off to a running start.
