Sega Dreamcasts and LAN Access? 149
I usually don't post nameless submissions, but this one was interesting enough that I figured it did deserve some attention. We've all heard about Sega's Dreamcast and how it has the capability to connect to the internet via it's 56k modem. So how does one go about connecting systems that are within a few feet of each other? Is it just me or do some of you think that Sega dropped the ball a bit when they didn't provide the Dreamcast with a way to connect to the local LAN?

The modem on the DC is a modular device, plugging into the "G2" bus -- a 16bit, 25Mhz secondary bus that's also used for sound data. It's got enough bandwidth. The ethernet adapter will replace the existing modem unit (it just snaps on/off).

So if all they want to support is POTS then well, as far as things look now, 56k is a pretty safe choice. Sure, broadband solutions will eventually take over completely, but the claim that momdem technology changes every six months is just no longer true. Maybe there will be some breakthrough in a while, but I have heard of nothing new in the works. 56k is already above (I think) what was supposed to be the theoretical limit that could be squeezed through the somewhat poor quality lines that are our telephone service.

I don't think this is the case. I have seen three different brands of cable modem and two different brands of DSL modems and both have plain 10Base-T on the back. The new cable modems @Home is using in Georgia have dual coaxial input and a 10/100 connection.
I don't have cable, so I'm not sure how many cable modems out there have Ethernet hookups.
I'm willing to bet all of them, since it makes little sense to invent new technology when 10BaseT ethernet is just so dirt cheap. Even if the cable modem doesn't need that much speed it's still much cheaper to get an ethernet card than rig some new proprietary connection. Although, some of the newer Motorola modems are using a USB connection. This is clearly not the option for techies since you can no longer connect to a hub and you are onyl supported with Win98.
Also worrying are those people who are now buying DSL modems on a card instead of an external modem with Ethernet jack.
Again, this isn't a move for techies since they will want the high speed connection to go to more than one computer (via a hub). Or, this is for techies who are smart enought to make that one computer the proxy/NAT machine and then put a plain ol' 10BaseT to a hub that has the other boxes (including the hypothetical high-speed DreamCast).
If you have an ethernet card on something, then by definition it support a hub...since the hardware is the same, just some connections (card to card or hub to hub) require a crossover. Assuming there was a switch to crossover or not (like on most hubs) this would be find.
I maintain that it would be way easy to ping or flood a Dreamcast connection if they went anywhere but a private network. Once I have the IP, it is maybe ten seconds work to get rid of some puny modem connection.
Or were you talking about ping flooding from the
