Yeah I know this. I was just curious since you mentioned desmodromic valve systems and continuosly variable valve lift since I wasn't aware of any aspect of the said design offering variable valve lift. Anyways, there has been much progress with desmodromic valve systems as well, for example take a look at the 2001 patent offered to Delphi Automotive Technologies (yeah, the guys who design/manufacture the GM Delco ECUs).
There are multiple systems that offer complete valvetrain control (needless to say camless) and of these, the pnuematic approach was used in the F1 racing arena for quite a while. If I am not mistaken, BMW is introducing or has introduced a production engine with electronic valve actuation. This is not new, if you look at the infrastructure development that has taken place for the last decade or so. For example, Motorola had demonstrated 100% electronic valve actuation systems applying their microcontroller and semiconductor products almost a decade ago. But one has to understand, unlike in say software development where there is a relatively small research to production time span (say a year at most), in the Automotive industry, the turnaround times can even be a decade or more even.
The main factors that affect the turnaround time is more than everything, production readiness cost (a prototype technology verified to work is far from production stage, where the technology has to mature through multiple generations of reliability testing, safety testing, production infrastructure development, technical skill propogation and finally, the manufacturing resource allocation) and above all, the need for it. Desmodromic valve systems have been around from 1910 and frankly, was not being used as it wasn't needed in production cars. As for Ducati, they have always been racing oriented and high RPM engines are the norm than a nifty feature.
If you are into the technology angle of automotive industry, have a look at SAE (Society for Automotive Engineer - http://www.sae.org) and go through the tons of reserach work that has been and is being done and you would realise where the R&D and production is relative to eachother. Having said everything that is being said, when it comes to many interesting technologies, with a reasonable budget you can experiment on your own and wihtout restriction (with respect to patents) if you are a hobbyist experimenter (non-commercial basically).
Good luck with you explorations.
"Any technology sufficiently advanced would be instinguishable from magic" -Arthur C. Clarke.
However, the flip side is, it's not magic, just advanced technology and at the end of the day, it's just application of science. Therefore, there is no magic that is beyond your grasp!
