Re: `buffer-list' and the frame-parameter `buffer-predicate'

[Alex Schroeder]

Perhaps you need to find the variable for ido or iswitch-buffer that
filters the buffers, and make it frame-local.  Then switching buffers
will offer different buffers based what frame you are on, without
interfering with low-level stuff.  Your idea would be limited to
user-level buffer switching.  The only problem is that you can only
implement this for buffer-switching functions that allow you to filter
the buffers.  But all interesting packages i know (iswitchb, ibuffer,
ido) allow you to do that.
