Mod_alias only uses paths on the local server, so that's not what you
are looking for. You probably want to use mod_proxy or mod_rewrite with
the [P] option for proxying.  ModRewrite would probably require the
least amount of apache configuration, once you get the right regular
expression that is.  

Something like "ProxyPass /~user http://machine2.com/~user" might work,
but to avoid putting a line like that in your apache config for each
user, you probably want to use a RewriteRule something like this:

RewriteRule   /~(.*) 	http://machine2.com/~$1		[P]
Note, I'm not terribly good with mod_rewrite, but this should get you
started.

You could also use the Redirect directive, but that would point your
clients to the other server so www.site.com/~user would become
http://machine2.com/~user in your client's url, and I don't think that's
what you want.
