LimeWire looks like it.

- Firewalls: supports downloading from nodes which are behind NAT and
can only initiate connections themselves.

- File contents authentication: When possible (depends on the peer's
client), files would need to match by a hash value (instead of filename)
to be considered "same". LimeWire also stores the hash values of
incomplete files on disk so that their download could be safely resumed.

- Reliability: Finding initial nodes to talk to is fast. Finding a file
isn't guaranteed -- it depends on what nodes you're connected to, ie.
you will only see a section of the network at a time.

Latest LimeWire does that.
