        Regarding most (or many) of the port changes--say, upgrading

        Why is this a bad idea!

The final form of actual binaries depend on a lot of things, e.g. which version of dependency you compiled with, which CFLAGS you have used, what options the port you built it. Some of these applies to packages as well, that's why I prefer ports over packages at all. E.g. let's see lang/php5. It does not have the apache module enabled by default. If it were, then the problem comes up with Apache versions. IIRC, 2.2 is the default now, but what if you use 2.0? How would you install php for your apache version from package? The situtation has been already pretty complicated with packages if you have higher needs for fine tuning, but you can use them if you don't have special needs. Binary diffs would be so complicated that I think this way we could really not follow.

If you need simplicity at all, use portupgrade with packages. It has an option (don't remember which one) you can use to make it fetch packages instead of building from source. Nowadays, this network traffic should not be a real problem, I think.

        You've brought up a lot of things I didn't consider; this was
        part of the reason for my post.  It seems to me that there would
        need to be some simple ground rules from the binary patches I'm
got in mind. The *default* CFLAGS in the port would match those in the patch is one place to start.
        Obviously, this could get way out of hand very quickly.  Two of
        my slowest servers (one 400MHz, 192M RAM) were rebuilding parts
        of the KDE suite; the new kdelib-3.5.6 [??] just finished and I
already scp'd it over to my more beefy platform. Once I've got all my servers up to date, it may not be that hard to keep them
        current.  You're right that bandwidth isn't a problem--um, in
        most places {{ clearing my throat! }}.  Bandwidth isn't the main
issue. It's time.

As you said, bandwith is not an issue, but time is, what I understand, of course. What I wanted to point out was exactly the same. For time concerns, you can use portupgrade with packages (somebody already mentioned with which option you can do this) and it will fetch the appropriate new packages for you. Binary patches would not make this process much faster if bandwith is not a concern.
