ssh doesn't scale in the sense that, if you want to connect to 700 servers at the same time, you have to run 700 separate instances of it.
Have you considered a push instead of a pull system? Put a script on your server that contacts you. Have cron run it repeatedly. The access method could be as simple as a POST request to a CGI script on your machine which stores the data locally, which naturally would be quite scalable.

CHSH(1) User Commands CHSH(1)
NAME
chsh - change your login shell
SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username]
DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one.
chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries.
OPTIONS
-s, --shell shell
Specify your login shell.
-l, --list-shells
Print the list of shells listed in /etc/shells and exit.
-u, --help
Print a usage message and exit.
-v, --version
Print version information and exit.
VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in
the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you
are root.
EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.
SEE ALSO
login(1), passwd(5), shells(5)
AUTHOR
Salvatore Valente <svalente@mit.edu>
AVAILABILITY
The chsh command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
