At first glance it looks like its similar to healbot. So it all depends on how they created the addon itself. With healbot, from what I could see, is that there is access to the main frame and thus the ability to attach it to a new parent and resize it using its own functions. If they haven't done the same to Vuhdo it might not be possible to integrate it.

For one thing, as I've noticed with wim when I tried to tie that in, can it be resized small enough to fit in the bottom right frame ?

Edit: Ah, reading it further it is looking like you are talking about replacing the raid frames in nUI with Vuhdo as an option. Scott I think is the best person to answer this as I believe he is working it up so that people could make their own setups although I am not sure using another addon in its place was one of his ideas.
