Here it is to be researched if this is specified in the IMAP standard (if
there any RFC that mentions this?), or if we propose a new RFC with such
an extension.

Until there is an RFC, even if you implement such a feature, there will be
no clients out there that will support it.

A good start, if there is no RFC, is the http protocol, that has
implemented the resume option. Like this you could even support parallel
download from couple of imap servers that are synchronized, getting from
each a small chunk (BitTorrent like with the seeds list being set to only
the servers).

Best regards,
