If you do that, you can forget ever keeping out anyone you didn't invite.
Not only can I give away the password (not that guest isn't the first
one I'd guess anyway) but I can do so without you knowing it
was me who gave it away.  If I've got my own, at least you can guess
that it was me that posted it to alt.2600, after 100 uninvited people
show up.

SSH again is the closest you'll get, I think.  Any other attempted solution will
not work across that wide a variety of machines.

My complaint about the happy hacker contests (yes, I'd like to poke
around in there when I'm bored) is that the machines are so heavily
loaded down with script kiddies, I can't get in.  Or, when I do, I can't
get a keystroke in edgewise.

Requiring SSH, then a unique name and password on the gateway
that had to be applied for, followed by having to have some account
on the inside boxen, will help keep the noise down somewhat.

Well, frankly, do what the porn sites do.  Understand that passwords will
be given away.  Then, you watch for the same account being used
simultaneously from many IP addresses, and flag it as compromised.

Would I not be leaving the compiler behind after I got it installed properly?

I forgot before... make certain that the inside machines can't get back out the
the Internet.  Otherwise, there is a BIG incentive to get into your playground.
