Llilum is still proof of concept, but the plan is to integrate the NETMF stack into the Llilum toolchain. Here's a quick note about this from Lorenzo's post
Ah, this may have been a somewhat misleading statement. It is not clear if there will be any shared code eventually, and what it would be. It's too early to tell. The toolchain (apart from VS) and the runtime are completely separate, and the APIs will probably be substantially different as well, at least for the foreseeable future.
Lorenzo made the positioning a bit clearer here:

"As llilum gradually comes online, we will see how to integrate llilum into both the netmf ecosystem and the llilc technology."
PS
Regarding dynamic loading:
"We do know that we will not support features such as dynamic loading with llilum, and that alone suggests that llilum will never replace .NET MF."
