I seem to remember some good stuff from Jonathan Sheffitz as well.
I can also email the very latest -- you can contact me using the username "jshefftz" using the domain from my friend's "www.nerandorace.com" website. (Or just PM if that doesn't work.)
To address the original question, yes, I will carry avy rescue gear for in-bounds skiing on days when isolated pockets of instability are likely to exist. (I'm talking about trips out west though, not my native northeast.) In some situations (like that Mammoth slide referenced earlier in the thread), patrol response can be very rapid, but just think about the logistics that would typically be involved...
For example, last year I was teaching at the NSP-East's Level 2 avy course, held at Whiteface, the only ski area in the eastern U.S. with lift-accessed in-bounds avy terrain. (Well, it's hardly ever open in the winter, but still.) For the final day of the course, we instructors set up a simulated avalanche site, complete with incoming ski tracks, simulated crown face, debris field, and two buried full-size dummies. (Yes, this took a looooong time to set up!) The students' collective response was pretty good, but still, the elapsed time from calling in the incident to when the first responders arrived was most likely too long to save a fully buried victim.
