Reading through the suggestions, I think the 5-point idea for VT q's is quite spiffy! Our practice group tends to do VT runs seasonally ... in our area it's more hazardous to drive to many winter trials, and our winter practice location is more than 200 miles from all 'local' trials. It's a time of year that club members trial sparingly, if at all, anyways. I wouldn't feel slighted in the slightest at earning fewer points, given the vastly lower expense. I wonder if there could be an app for that ... that has current trial locations in it, so when you log in to submit runs, you enter your gps'ed VT run location, and it automatically allows/disallows you based on your location being valid, or not.
The idea of only posting two sets of courses per month seems very reasonable, too.
What about a sign-up form (and maybe a processing fee?) for a club, group, or individual to become a 'certified host' of VT runs? This could come with signing something saying that one agrees to abide by the code of conduct, etc., and understands that there are (x) repercussions if the rules are found to be broken? I find that often the simple act of having someone put their name to paper makes them take things a bit more seriously. This might help with the validity issue, because there will be a go-to party who knows they will be held accountable.
VT's have been a fun way for our group to change up our winter practice routine, and have been a great way to introduce newer folks to what to expect at 'for reals' trials, too.
