No, what he needs is simply windowed protocols, as you suggest.  The best
two packages/protocols you can use, in my experience, are PROCOMM's windowed
Kermit, and Telix's SEAview.  I tried SEAview for the first time about a 
week ago over Telenet's PC Pursuit package, and I was amazed.  It took only
an extra 5% of time over a normal, local transfer, as opposed to the XMODEM
family (non-windowing) that takes 3 to 4 times normal time over Telenet's
packet network.  Both PROCOMM and Telix have the shareware-type money that
you're supposed to pay them if you decide to use their package, but it's
quite inexpensive compared to the commercial packages out there.
If you cannot find either of these windowing protocols, YMODEM is the next
best thing, because the data stream is interrupted for CRC or checksum stuff
only once every 1K of data, as opposed to XMODEM's 128 bytes.
