You have now met my friend named "JVM startup" :-)

Yes, you could probably get that down to less than 30 seconds by only
starting a single JVM in a batch job and communicating with it from RPG
using data queues.  Though I shouldn't speculate too much because I haven't
been on a machine with only 1GB of memory in a loooong time.  This is the
same approach I use for RPGChartEngine (
http://mowyourlawn.com/RPGChartEngine.html - free and open source).

 What is your timeline for needing it?  Maybe we could trade some Java open
source work for some RPGUI open source work :-)
