A separate connection (do *not* do this within the disterl connection).

Beyond that, whatever feels appropriate. Do you need to be able to restart in
the middle if there is a failure, is a partial failure OK, is restarting the
entire transfer OK instead, etc? Should this be throttled in some way based
on an external input?

There are a lot of little details that might come into play. If you just
read/write file->socket->file in a naive way it would work fine, but file
transfer requirements are usually a tiny bit more involved than that.
