Not yet.

Multidoc is trying to mimic mdi, I've tried it once and I didn't like it.

MDI started few days ago, only qt fully supports MDI on all targets where it 
works under lazarus (mac, linux, win).
Gtk/Gtk2/Carbon isn't finished yet (depends on mdiemulator).
Win32 will have native implementation (same as qt).

Because, mdiemulator isn't ready yet. I don't want to commit 
partial/incomplete solution.
