Right so far.

Nope. You'll have to mark the packets with ipchains (or, in your case
iptables) first (the -m option for ipchains, --mark for iptables). Then
you add a rule matching on that fwmark (ip rule add fwmark 0xf00 table John).
Note that you have to specify the marks in hexadecimal, or else it won't work.

I'll leave figuring out the ISP-specific routing to your creativity... 
can't really spoil all your fun, now can I? :)

Doei, Arthur.
