At least as far as CE is concerned, you need at least 8Mo to run a java VM. This is due to the size of the classes however. On the other hand there are smartcards which have an embedded VM cf: (URL) believe the VM can probably develloped but the (...) (26 years ago, 22-Feb-99, to lugnet.robotics.rcx.legos)
