The closest you would get to that would be DLC for Skies of Arcadia, Phantasy Star Online, Samba de Amigo, Chu Chu Rocket!, Sonic Adventure, Sonic Adventure 2, and Rayman 2, as well as custom graffiti for Jet Set Radio, and maybe some extra VMU minigames. There was also a modification to the Dreamcast bios screen that was activated through Puyo Puyo Fever that
maybe required online functionality in order to access at the time... I'm not certain on that one, it may have just been accessed off of the game disc through an option or achievement.
All of this DLC is available on the game discs from the start, though -- it just took little VMU files (the one I used for Skies of Arcadia was only one block) to unlock them. Definitely not worth the price of the Broadband Adapter (or the headache of other methods) to access, since all of this information has been preserved on homebrew apps such as the
VMU Backup CD, and the Puyo Puyo Fever and Jet Set Radio customization can be done through the wonderful
VMU Tool. I'd strongly recommend picking this up most of all, though: the
Capcom Fighting Collection. It's basically the most insane thing anybody ever made for the Dreamcast -- VMU Backup CD + Action Replay to boot imports + about 1/4 of Capcom's output for the Dreamcast + Ikaruga + other goodies.
In terms of added content, the only other thing I could think of is an adventure game creator called DreamStudio -- I know that it had some sort of online component that may have allowed for players to trade their games with each other (makes me wish that there had been a Dezaemon release for the Dreamcast), but I seriously doubt that any such function could be accessed so long after 90% of the servers have been pulled.
I do know that NullDC offers online functionality, although I have no idea if it emulates any of the old SegaNet stuff, or if it just simulates local multiplayer through the Internet. Anyway, the only up-and-running Dreamcast online title that seems interesting and can't be played more easily on a PC is Planet Ring. So you'd basically be shelling out $100 for a Broadband Adapter so that you could do various (admittedly very cool) things that you could do much more easily through a PC/Dreamcast homebrew disc... and play Planet Ring.
...I kinda really want to play
Planet Ring though, to be perfectly honest.
