As for Hamachi, its a program that allow you to tunnel to someone's IP without portfowarding/dmz/similar stuff in order to play online. You dont need Hamachi for Lan

Would you say that there have been compatibility issues fixed using builds? i.e. Lag during multiplayer, or overall multiplayer functionality for a title that was not working.

Lag is depends on your connection between you and the another person. The farther you than the person, the laggier it gets. Bad internet company also a factor
Some games have different multiplayer system. Kinda hard to work with that unless someone devote their time to fix and test every games that have multiplayer
