Syncing two wordpress sites

Hi,

I’m making a membership based site (using amember), and because I wanted it to show a different menu in the members section, I’ve installed wordpress twice.

There will be 1 page on both the logged out and logged in site that the client will be editing regularly. Does anyone have any idea how to sync these two pages? This way the client will only have to edit the page in members/wp-admin/ and not in both.

So any ideas as to the most efficient way to do this? I’m currently thinking of some way of using the membership sites RSS feed to acheive this but I’d like some input first.

Thanks
