Hello Idan,
well, you usually do that by simply using "subprocess" as in
```ruby
Ruote.define do
subprocess 'do_that_other_thing'
end
```

No, there is currently no way to pass an existing Ruote::HashStorage. If you
need that, I can add it to master.
Another way, though:
you can set :engine to nil and that'll run the subprocess locally:
```ruby
Ruote.define do
subprocess 'do_this_other_thing', :engine => 'engine_x'
subprocess 'do_that_other_thing', :engine => nil
end
```
which is equivalent to:
```ruby
Ruote.define do
do_this_other_thing :engine => 'engine_x'
do_that_other_thing :engine => nil
end
```
which is equivalent to:
```ruby
Ruote.define do
do_this_other_thing :engine => 'engine_x'
do_that_other_thing
end
```
Perhaps you prefer to use:
```ruby
Ruote.define do
engine_x :pdef => 'do_this_other_thing'
engine_self :pdef => 'do_that_other_thing'
end
```
In that case, tell me and I'll add a way to pass an existing storage when
registering an engine participant.
Kind regards,
