This should be simple, even with an ftp layer.
Do you need to worry about copying a file while being written? If so, you can detect others on the file with fuser. Can you wait on the writer to finish, near term? Are there other local readers that would confuse fuser? Can you make the files you want to move read-only, immediately once created, so implicity there are not being written?
First, both sender and recipient will cd to the head dir over the subtree in question. I like to use "find * -type f -newer /elsewhere/mark_file ! -newer /elsewhere/mark_next" and a marker file created with touch. 'touch' a new file at the start of every cycle, /elsewhere/mark_next. Then sleep a second so anything written in that second and also the next will be excluded. Sleep longer if it helps eliminate files being written. After the find and send, "mv /elsewhere/mark_next /elsewhere/mark_file" to support the next batch, seamlessly. Pipe the find to a "while read f" do loop that knows how to check for writing users and ftp the file using relative paths. If the files to be moved are read-only, test with 'if [ -w "$f" ]' and if writable, 'touch' their modify time forward so they are considered on the next pass.

NAME
ftp - FTP client configuration file
SYNOPSIS
/etc/default/ftp
DESCRIPTION
Use the ftp file to configure the behavior of the FTP client. Lines that begin with a hash symbol ("# ") are treated as comment lines and
are ignored.
Behavior Directives
The ftp file supports the following behavior directives:
FTP_LS_SENDS_NLST=yes | no The ls command of the ftp client sends an NLST to the FTP Server by default. Several non-Solaris clients send
LIST instead. In order to make the Solaris ftp client send LIST when the ls command is issued, set
FTP_LS_SENDS_NLST to no. The value of FTP_LS_SENDS_NLST is yes by default.
If the user sets a value for FTP_LS_SENDS_NLST in the user's environment, this value will override any FTP_LS_SENDS_NLST directive that is
specified in /etc/default/ftp.
