Will this multi-home setup be co-ordinated with a single ISP?
The problem with this setup is that most ISP's can not guarantee which
LNS your ADSL will connect to, ingress traffic may not be load-balanced,
or may not work at all.

Yes, but we need a few questions answered first.
- one or more ISP's (are you looking for ISP redundancy)
- will this particular site be the VPN end point for the other sites
(and do you have other ingress traffic to this site, ie web server,
email server etc)
- is your ISP(s) co-operative when it comes to changing their network to
suit it's clients
- does your ISP(s) support multi-link (aka bonded, aka bundled) ADSL links
- are you looking strictly for load-balancing, or do you want redundancy too
If you don't get too far here, you may want to migrate the thread over
