InDesign actually has quite a bit of Frame-like features, including straddled heads. Not everything, of course, but a lot and more with each version. Some things, like tables, typography, graphics, and ePubs are much more advanced in InDesign. Generally, it is RTF as the middle man that lacks the functionally.
I should have mentioned the excellent Mif2Go. A must have utility. Another option for converting Frame files to InDesign is DTPtool's Mif Filter for InDesign.
