Hi Paweł,
Creating new actor is cheap, but you will have to bother with destroying
it. Otherwise you will have a kind of memory leak.
Anyway you shouldn't block in actor's receive function. This can be easy
solved by using pipe pattern:
http://doc.akka.io/docs/akka/2.3.8/scala/actors.html#Ask__Send-And-Receive-Future
PS
This is my opinion, but I think you should consider using akka futures
instead of actors. Actors are usable only when you have well defined
hierarchy or you have to manage internal (and mutable) actor state. It
seems to me that both of those don't apply to your case.
Regards,
Paweł
