Currently I completely lack the time to work on the validation plugin, so can't really offer any help on this.[...] So, what can you recommend? What might be a way of accomplishing this within what exists already, or should I try to create something independent to handle this sort of scenario?
With that in mind, I can recommend that you try to create your own solution and share that - odds are good that we find a nice way to integrate it later.
