More details:
It's important to be able to send a request to one specific server and
get one response back. Two variants would also be useful: 
- Send the same request to a group of servers and expect one response
from each (correlated with the request sent to that server). Each
request/response pair would be blocking, but the client could
send/receive the many paired communications in parallel. In other words,
it is not necessary to receive all the responses at once or even in any
- Send the same request to a group of servers and receive only the first

It's easy to get carried away with requirements. For example, it would
be nice to distinguish between two timeout scenarios: the request takes
too long to reach the server OR the server receives the request, but
takes too long to form a response.

For now, pointers to anything available are a help!

Thanks again,
