[p2p-hackers] simulator for p2p

[Davide Carboni]

Hi,
is there any way to simulate a p2p network  using a single PC?  I know
ns2 but it seems very "low-level" simulation. I'd like something to
simulate a network of peers abstracting from the serialization of
messages. For instance, I'd like to model peers like objects in memory
which exchange messages invoking methods each other but taking into
account variables like the bandwidth, the latency and so forth.

Bye,
Davide
