Whooops! Sorry, I missed you message, Mike!
Unfortunately, not right now, but I am working on line / sphere collision testing, which could be used for picking (although it won't be 100% precise). I will upload a sample on how to do screen picking with that, although I will probably add real picking soon.
I have been busy lately, work is not letting me dedicate much time to Vortex2 these days, but I have been working on a better shader architecture (to allow you to use custom shaders) and the ability to enable a separate depth pass when rendering that should improve per pixel lighting performance.
