Chris,

Had you had a look at pfSense and the dual-WAN functionality? I haven't 
yet had a chance to look at pfSense myself but from what I have seen you 
  have the option to profile which IP traffic goes out on each WAN 
connection and/or load-balance on a per-connection basis.

I feel a bit guilty for recommending 'the other side' but there seems to 
be enough synergy between the projects for me not to cause any offence. 
Running everything on one box with one configuration has got to be less 
of a headache than getting into virtual firewalls :-).

Best regards
David
