Oleg,
This is a fair amount of work, but you may be able to subclass a
version of java.nio.channels.FileChannel to read/write only to
memory, and then use the lower-level GeoTools ShapefileWriter and
DbaseFileWriter classes to write to your memory-based FileChannel.
This would get you an in-memory representation of the shp, shx, and
dbf files.

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
