I would think it's easier than mapping gates.
I have not ever looked at LADSPA code. I assume most people write in C. 
Today's DSPs, even 10 years ago, have a full compliment of C programming 
tools. Bingo.

Of course, the goal would be to strike a proper balance with making it 
easy and cheap to design and mfr with making it easy and inexpensive for 
the end user. From what I've read, that is your profession! I have 
always said that engineering is an exercise in compromise ;-)

It would be a cool and fun project!

Have you seen plugzilla or receptor?
http://www.plugzilla.com/overview
http://www.museresearch.com/receptor_overview.php

Kinda what you're talking about?

I think they created a VST wrapper to run in Linux. I would bet the 
creators of one or both of these products visit this site.
