I'm planning on a 128 MB system, possibly dual processors if the need
arises. That way, the OS should be able to cache the FS fairly well,
so maybe all those writes wouldn't be so bad afterall..especially if I
keep flushes to a minimum...

I'm definaly not going to write a custom caching mechanism...much easier
and probably better to use the OS.

I'm going to have to read the java docs and books a little more closely
before I'll know if that makes sense or not :)

Heh, what fun is a completed project! Besides, it is not too OO and
there are a million muds out there already...there are virtually no games
like what I'm proposing (that I know of at least..)
Btw, there would be a possibility of going comercial... I would consider
trying to work as a group with someone. The part I know least about is
the GUI end (I'm thinking polygon rendering with bitmaps filling the
polygons.) This will not happen quickly, and it is a hobby, as I already
have a full time job..but I am dedicated to the project. If any of you
are interested, drop me some mail...
