Is there currently a way to add custom settings under PageSettings? (other than modifying mojoportal code)

I (successfully) developed a custom module for my client that will re-direct a user if their IP address/country doesn't  match specified criteria. (As example, my client has a global market, but some of their products are only available in North America. So if a visitor is NOT in North America, he/she is redirected to other content in the site).

But now my client's requirements have changed. They want to have a page shown or hidden in the menu system based on IP address, which is why I asked about the ability to add custom Page Settings in this thread.

I was wondering if anyone in the forum has tackled this situation?

A couple of options I've come up with are:

1. Create 2 different pages menus (based on 2 different branches in the sitemap) and test for the IP address in the layout.master
   
   •    Upside: Not changing core mojoPortal code
   •    Downside:  maintaining 2 sets of page menus
2. Add a custom field(s) to the Page Settings (to specify if an IP-specific page), then test for this setting in PageMenu.ascx.cs (and in any other affected page)
   
   •    Upside: Easier to maintain; only one menu system
   •    Downside:  Changing core mojoPortal code

Any suggestions, ideas, or solutions welcome! Thanks.

Jamie,

Thanks for the input.  The javascript approach may work, since security isn't really an issue. 
I could assign a css class to the the page's Menu CSS option, and use a Javascript Onload to hide or show.

Thanks again.
