Intel is starting to ship with 1/10GBASET LOM IMO this will push the market
to BASET, that and the cost is radically less. If you add up the SFP+
optics and cabling costs these are easily more than many ToR switches. Also
there are dense 10GBASET switches that can run at line rate and drive
distance to ~100M, since this is a Cisco focused mailer I will leave
company names off...

While the BER is a bit higher on BASET the above can be done today
