Hello! That agrees with a discussion I had with one of the people behind that project. That took place during the third and final US based Maker Faire, this past September. I am interested in one because of that reason. ----- Gregg C Levine [email protected] "This signature fought the Time Wars, time and again." ------------------------------------------------------------------------------ Ridiculously easy VDI.
