steinberg seem to be doing it, and it's UK / London based staff.. coincidence that an ex dev-team from the main player in that field was based in London? 

from the mail I got.. 

New Steinberg R&D center in UK
Steinberg is elated to announce the opening of a new Research & Development center in London. In the new UK office a team of highly skilled developers and product specialists will focus on developing software for the music notation and education markets.

Maybe time to send in some suggestion.. perhaps a way to bridge the current DAW midi tracks to the new software, so you get real time notation update (or a one button batch update) as you record/edit midi track from your favorite DAW. 

Well.. that's how I would use it (not using the notation view to draw notes, but use the DAW to record/edit midi).
I was hoping Notion could do this level of integration when Cake suggested it..

seems like some of the ex-sibelius staff are now with steiny.. and to be honest I really hope it does avid/m-audio over, after how as an end user they seem to have dis-regard to even answering a simple email due to their buggy drivers

notation could REALLY gain ground at this time, it's a really big market what with education sector etc
