Resources on "Inter-Church" Marriages

Can anyone link me to any good resources concerning inter-church marriages. I am not really concerned what perspective they are from (Catholic, Orthodox, or Reformed).

I am specifically interested in the issues that will divide/unite in such a marriage. In addition, anything that gives insight on how to make them work.

Thanks!

edit: By inter-church, I mean between different denominations of Christianity. (like those listed above)
