I'd be a little leery of having mindmapping in OmniFocus, considering it hasn't been done well in Omnigraffle. I'd suggest just keeping mindmapping in a dedicated app and just make sure it has .OPML support so you can get your data out and into OF.

Here's my workflow in regards to mindmapping and GTD:

. Start with Mindmapping (iThoughts on iPad and/or Novamind desktop)--iThoughts exports native NM files --
. Get the entire scope, vision, and bifurcations out and on the page
. Create a branch of Next Steps
. Create a branch of Someday
. Create a branch of FollowUp
. Copy these branches
. Export to .OPML
. Import into Outliner
. Copy and Paste into my Projects in OF
. Rinse and Repeat as needed
