Nope, but you can use a 2-pole arc fault breaker. They are available.

How does the price compare?

I have only used the Cutler-Hammer 2 pole AFCI breakers and the cost was the same as 2 single pole breakers. This makes them worth the effort to get them in my book. Is anyone else making them in 2 pole yet ?

When I last bought, it was maybe 10% more than two, single pole AFCI's. They make them in 2-pole independant trip and 2-pole common trip. Either one with work with MWBC's.

If not a DP AFCI breaker, you can run 12-2-2 (black, white, red, white w/ red stripe) Not exactly a MWBC, but still only one cable for 2 circuits.

Arc Fault...try using a 14-2-2 romex

When I pull bedroom circuits (long distances) insteading of using a 14-3 and not being able to share the neutral, I use a 14-2-2. It has a Black, Red, White, White with red strip and a ground. That gives 2 neutrals and 2 hots for your arc fault breakers and keeps one bedroom on if the other one has a fault condition.
