The future looks very bright for polymer fiber, which can be processed with a simple sharp knife (100 MBit/s Ethernet kits + converters are reasonably cheap, 1 GBit/s is being developed -- 10 GBit/s might be rather challenging, unless there's photonic crystal technology). -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
