Sounds good.

How about RETR ? Seems pretty clear to me.
Do you mean like:
open: pop-async://blabla/retr/auto
(That would do everything as fully automatic as possible).

Do you mean protocol waits until all mail is downloaded into memory,
then delivers a big block of mails in one go?
That's alright.
I would be happy if it's buffered as long as I know there is a
/direct mode allowing email-by-email and also chunk-by-chunk
download coming soon. :)
Perhaps a max size could be specified (like 10MB for instance),
emails larger than this size would be downloaded using a specified
disk cache file in /direct mode.
I would like the following degrees of control:
1) Fully automatic, buffer everything,
good if all your emails are rebol-list mail only :)
2) Notify as each mail finishes downloading
3) Notify as each chunk of data comes down
4) Notify on a regular schedule, no matter what the situation is,
tell the user what the protocol state is.
That's roughly in order of granularity, from less detail to more detail,
though you could have different combinations of some notifications.
This makes me think of a feature request:
Order the mail in order of increasing size before downloading,
so you get lots of small mails quickly (which gives a good
user interface feedback) and can start reading straight away while
the larger emails are still downloading.
Shouldn't forget the original order though :)
How about:
open pop-async://blablabla/retr/order [decreasing size]

That's good.

Either is good, use whatever you are using now.
