Multiple External Interfaces - 6.Nov.2007 5:43:19 AM

Hi,
I understand that ISA200x cant do true load balancing on external interfaces to mutiple ISP's, but i wonder about this..
 
I currently have 2 ISA 2004 SE servers,
 
ISAa goes to ISP1 and routes all server traffic, e.g. VPN, SMTP, WWW (hosting)etc
ISAb goes to ISP2 and routes all user traffic, e.g. WWW (browsing), FTP etc
 
This way, our users wasting time and bandwidth dont interfere with the core server traffic.
 
I'm planning on moving these onto two new ISA2006 EE boxes, and they are currently under an Array, with NLB on the internal side, and an interarray network between them.
 
Is it possible to create this array so traffic still flows as previously set up in ISA2004? I cant really buy anything to stick in front of the ISA servers, i just want one array to manage rather than two seperate ISA's. If ISP1 or ISP2 fail, i can manually switch the traffic down the other line accordingly. I'd also like to use multiple incoming MX records for ISP1 and ISP2 in the event of failure of the lines, but previously doing this with two seperate ISA 2004 boxes proved a little tricky with the publishing side.  
 
Any clues\assistance would be fantastic,
 
Thanks in advance,
 
Tom
