party:::cforest can do, here is an example:

y <- matrix(rnorm(100), nc = 2)
x <- matrix(runif(50 * 5), nc = 5)
dat <- data.frame(y = y, x = x)
cf <- cforest(y.1 + y.2 ~ ., data = dat)
predict(cf)

gives

> predict(cf)
                y.1          y.2
  [1,] -0.300622618  0.318143745
  [2,] -0.270218355  0.331261683
  [3,] -0.330129113  0.308545082
...

Best wishes,

Torsten
