Parsable pocket dictionary file

I'm writing a simply dictionary program which I hope to port to embedded (it's currently J2SE, will port to J2ME for cell phones), but am having a hard time finding a reasonable data source for it. Most of the resources I've found are from 1995 full of long-outdated FTP links. Project Gutenberg has a Websters going, but it's far too massive.

I've got to keep the JAR to <= 500kb, so uncompressed (I believe that midlet allows for the JAR to be compressed) the dictionary should probably be < 750kb.. does anyone know of a dictionary I could use?

Do you want a wordlist, or a dictionary with definitions?

/usr/share/dict/words is about 2MB (on any linux/mac box)... you might be able to trim it down :dunno:

How about compressing it? Even a simple method of just replacing the most commonly used words would reduce it by a good amount. ;)

Since it will be in a JAR file, it should be ZIP compressed, which would help. I'd like definitions.
