Sega could make an absolute killing off this; if they brought back the BBA and priced it even $50 or so, that's not a bad profit. Sony's Network Adaptor goes for about $45, and Nintendo's is around $35. Of course, there isn't a global desire for Dreamcast hardware, but a limited distribution through Sega.com could bring a profit to Sega, and a product that the DC community could enjoy.
A petition brought Border Down to the Dreamcast, if anyone is interested in starting a petition to bring back the BBA, I think this thread is a good place to start.
