Sounds like the OP has most of what he needs to know. Thought I would add a reply I sent ot a friend a couple of weeks ago while he was doing the same research as you. Here's a slightly edited version of what I sent him.
Also you can see my review of it from November 2015; http://www.enworld.org/forum/showthread.php?386930-Fantasy-Grounds/page6&p=6750807#post6750807
Thanks for this LordEntrails. Actually I did see that (I've gone through some of the older threads on this) and I appreciate the information. On the topic of pricing, if one gets the ultimate license, that basically really just covers who can access / play with the DM and how much they, the player would pay.. It also includes the 5E SRD (and some other rule sets). However the PHB; DMG and MM would still need to be purchased. If the DM buys the books, it is my understanding that everyone that connects to that DM's game would have access - is this correct? Also, are the players able to 'gift' books to the DM?
I just want to say thanks for all the replies so far.
