"can you play arrpegios fingerstyle?"
I'm more of a pickstyle player, but i've been taking classical lessons in the past few months. To me, playing arpeggios across strings (never more than one note per string) is easier with the fingers. While these can be swept with a pick, to keep them even and in time i think that it's usually easier fingerstyle. The crossroad arpeggios, since they have more than one note per string, become more difficult and complex, and to my mind are easier with a pick. Somebody like elliot fisk, however, I'm sure could blow away most pickstyle players using his fingers on arpeggios like that.
