Allow PCGen to support Server-based gaming / Expand Server uses

From a non-code perspective I can see this happening a couple of different methods:

Like we have for our testing, we have a preset character (GM Made?) that is the approved Character, then the player submits the changes, which then generates a line by line Log of the changes against the GM's Copy. Possibly the easiest implementation to deal with.

2nd Method - GM Machine or Server hosting the files - This would make PCGen be a client mode. The files would all be there, we can get fancy with password access and such, but this would be more intensive work - Don't see this happening anytime until well after CDOM completion.

3rd method - Kinda like the 1st method - instead of just a log, the character file sent to the GM is sent with the Changes flagged - the GM would then approve or roll back each change made. Probably a little more UI Work, easier to implement than method 2, definitely more work than 1st method, but probably closer to the users request.

I have lots of experience with a server framework that would take care of the server-client interaction and is written in Java. With some coding you could have the client send updates to the server without a need to send the character file. To start this can be implemented. I could do this isolated with an accessible API (probably using listener registration approach) so it can be hooked in the proper place afterwards, as I'm not that knowledgeable yet.

Feedback?
