Old fan of ViTP. Never dipped into doing it by Vassal or Cyberboard, my belief has always been board games should be board games and computer games should be computer games.
Hadn't played it in years but pulled it out recently and forgot how much dice rolling happens.
Be sure to check out Fire in the Sky from MMP. Single session grand strategic PTO game also, with several neat mechanics like how the Japanese player is entirely dependent on his oil points.
By the way, if you weren't already aware L2 is coming out with an updated reprint of ViTP. Haven't seen any new news on it lately though. They already have the reprint of War at Sea out. Been out for a while now.
