I did RP a brother-brother relationship in my super early FFXI years. It was by far one of the most memorable experiences I've had in RP overall. There wasn't a ton of planning involved or anything. I don't even remember how it started. I think I posted a thread somewhere about looking for someone to play the role and he volunteered. We matched up stories and made it work. Awesome experience overall. I sincerely hope that I find at least one person to play a sibling role again eventually.
The only bad thing about sibling relationships (or any relationship for that matter) is if/when that person decides to quit RP, quit the game, and/or just drops off the radar. You kinda get stuck in a bad position then. Thus you're forced to be rather selective in choosing someone who you know will stick through everything for the long haul. That's not always easy if you don't know the person very well.
