Hello again!
Thanks to all the advice you guys have given me, I have set up an online scoreboard for my cabinet.
Its very primitive html right now, and I'm welcome to any help to develop it farther.
But here
emulatron.zapto.org is the link, I'm just using a simple noip.com domain instead of buying one.
The process:
Made mame save highscores to dropbox
Had maximus arcade launch a bat at startup containing commands to delete the files, then write new .txt files off of the .hi files using HiToText
Linked the files (via dropbox) to the website.
Its a bit of a pain to add a new game, but it works!

EDIT: would like to thank CoryBee and Scott for helping me prevent viruses by connecting the cab to the internet, and just general help
