... so hopefully clients will not be baffled by the file type or icon.

I am afraid that remains to be seen. Depending on the way the clients computers are setup and their own knowledge you can still have all sorts of problems. I have seen all sorts of stuff and unfortunately most clients start calling you first instead of looking for the problem themselves let alone solving them. In 99,99% of all cases the problem turned out to be on the clients side and in most clients they blamed me for it
I have had clients complaining about the fact my colors might be right but since their screens are way too blue and really shitty my files needed to look good on those screes and not on my screens (or on any high-end calibrated screen, try argueing with that).
I delivered the wrong file when it printed green on an office deskjet printer.
I was to blame when they had the wrong password in their browsercache for the ftp site or simply forgot their password.
Some are baffled you cannot email a 224MB tiff file let alone a set of 50 images.
The amount of time I spend in solving all sorts of client side problems is immense, I sometimes just want to scream, 'go get a clue and educate yourself or hire a system administrator that knows his stuff! ' or even much worse depending on the mood I am in
You can solve the non-showing extention or the association on your own machine but it doesn't say anything about what is going to happen on your clients machine.
