If you live in a single house, the power sub-grid is likely to be confined to your house or even less (I cannot get EoP from my house to my shed, different circuits). If you have offices in an apartment block, most of them will probably share the same sub-grid What I am saying is that you have to be aware of this potential issue, and best treat it the same as a wireless signal and make sure you do protect it eg with encryption if you transfer confidential information across it Horst _______________________________________________ Gpcg_talk mailing list [email protected] http://ozdocit.org/cgi-bin/mailman/listinfo/gpcg_talk
