This afternoon I specified an improved interface for netclient that
would allow such downloads:

https://gps.dynxs.de/svn/lib-netclient/trunk/new_http_client.mli

This new API uses Netmime classes to represent headers and bodies. In
particular, the bodies can be backed by files (or by whatever storage).

PXP can read directly from Netmime's bodies (using the function
from_obj_channel).

Since this is not only an API change, it will take some days to
implement this (I hope < 2 days; I have some time now, so this will be
done soon). There are still some open questions, especially concerning
future extensions (e.g. SSL).

Any comments on this plan are welcome. I also attach a conversation with
Stefano Zacchiroli that explains this quite old plan.
