Running multiple *.feature files

Currently there is no way to run behat with multiple *.feature files in one execution. 
Use case is running suite in parallel. I want to run half my features on one server and another half on the other.

For example

``` bash
bin/behat $(find ./features -name "*.feature"  | sed -n '0~2p'  | tr '\n' ' ')
```

but currently it throws RuntimeException "Too many arguments."
