Anonymizer tool like Tor?

[Gilles]

Hello

I'd like to download information from our competitor's web site,
without their knowing it's from us.

The Tor network works fine, but they don't seem to provide a *nix
version, much less a command-line version (the download script will
run  on a non-X FreeBSD 6.3 server).

Do you know of an alternative for FreeBSD, ie. a solution that will
let me connect to a web server through at least one other host, and
have the IP address change automatically every few minutes?

Thank you.
