Ummm, I think it will be opening a real can of worms if your 'proxy'
record causes any third party who has not explicitly requested you do
this on their behalf, loose some mail due to it.


The proxy is really intended to satisfy includes which would otherwise break a valid record. All the operators within the proxy are given as ?ip4: and the include from the users record itself will be ?include: so there will be no "fail" because of the proxy, and there will be a lot of "pass" results which would otherwise not happen.

I've got several ISP's on the request list now
cox.net
comcast.net
rogers.com
vianet.ca
sympatico.ca
blackberry.net



Anyone got any more?

No, but I think you can strike sympatico.ca off the list, they are publishing now:
[root(_at_)bigone5 logs]# dig -t TXT +short sympatico.ca
"v=spf1 ip4:142.182.48.192/27 ip4:206.172.20.49 ip4:206.47.72.90 ip4:206.47.60.9
0 ip4:206.47.199.0/24 ip4:209.226.175.0/24 include:hotmail.com ?all"
[root(_at_)bigone5 logs]#
