"How long is a piece of string"? Seriously, without knowing what resources or experience you have available, all that can reasonably be said is "yes, it's possible". There's at least one product I'm aware of using a cut-down FreeBSD on a 386ex in 2MB of RAM. I think that still has networking in the system too. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
