Brad, I was referring the html 5 storage features like local storage,
filesystem, indexdb mechanisms in the above comment .. on how they are
inadequate/add overhead when I need to store a media file. local storage is
not useful for media since it's based on strings. Filesystem and indexdb
will work but there is some effort in either base64 encoding and/or using
ajax and/or using blobs and/or url redirections when all this can be solved
by just exposing the appcache APIs to add/remove entries.

ok, I'm totally new to this .. So from what I understand webkit is part of
IOS (in case IOS) and is not included as part of the browser like on the
desktop versions (please correct me if I'm wrong here) ?? If this is true,
any feature even if I want to add has to get accepted in webkit community
and get released as part of the official iosX build ? That seems lenghty ..
Is there no way for me to add the changes and test them out on ios4 ?
apologies if I'm asking the wrong questions here and would appreciate if
you could point me in the right direction/mailing list for this ..

I guess this requirement is clear now.  Sorry about the confusion .. The
part about appcache not supporting media files was limited to ios4 which I
explained above. I was trying to say that dynamic appcache would be helpful
in the sense that adding/removing media files would be much more efficient
than using the html5 storage methods from my understanding.
