Faraday Adapter Parallel Requests On Multiple Domains / Connections

Looking at Faraday's wiki page on parallel requests it looks like we can easily handle parallelization for a single connection:

conn = Faraday.new(:url => "http://coolness.com") do |faraday|
  faraday.adapter :typhoeus
end

conn.in_parallel do
  response1 = conn.get('/one')
  response2 = conn.get('/two')
end

But if I wanted to have parallel requests between multiple domains / connections, it seems like the Typhoeus Faraday adapter does not support this. To be more clear, I'm expecting something like this:

conn1 = Faraday.new(:url => "http://coolness.com") do |faraday|
  faraday.adapter :typhoeus
end

conn2 = Faraday.new(:url => "http://hotness.com") do |faraday|
  faraday.adapter :typhoeus
end

manager = Faraday::ParallelManager.new # this does not exist of course...
manager.in_parallel do
  response1 = conn1.get('/one')
  response2 = conn2.get('/two')
end

Is this a planned feature for the future? Or maybe with advanced usage is it possible to pass around the Typhoeus managers into the different connections? Like:

manager = Typhoeus::Hydra.new

conn1.in_parallel(manager) do 
  response1 = conn1.get('/one')
end

conn2.in_parallel(manager) do 
  response2 = conn2.get('/two')
end

Thanks in advance!
