Welcome to Gaia! ::

I've done it successfully before, I think the problem is that you need dedicated players who are actually willing to work hard and follow the rules. I'm actually currently attempting to get one started right now, but there aren't a huge amount of players interested at the time being. I often forget that not everyone is as passionate about my game system as my college was - there were 20 or so of us who loved World of Darkness and who played it all the time, heh.

I don't know if it would be popular online since people tend to have vacillating schedules. Like Slaine said, I think it would be hard to find a group that were really committed to taking time to go through all the stuff.

Personally, I'd say all the rules are a little bit too much effort for what you'd get out of the roleplay, especially since you lack the physical presence of the other players (no drinking or joking around a table, right?).

However, I think that incorporating a few of those mechanics into a roleplay would be really interesting. Instead of coming up with a story that the players agree on and can think up in advance, they'd be forced to react based on the roll of the die.
