Well, they did say they had done proof of concept tests; and that they could build a base station for $8000... So might not be completely impossible... -Toke _______________________________________________ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel
