Source is not currently available, but we expect a limited release sometime
in the future.  No ETA is currently available.

You should see slight differences.

In v2.002 of the client, you can set the environmental variable RC5INI to
the full pathname of the inifile to use.

The buffer files are intended to be shared by multiple instances of the
client, so there is nothing wrong with it being in the same directory as
those used by other clients.  Yes, file locking is dealt with properly.

You can either use the environmental var trick, or rename the executables.
The ini filename is derrived (if not specified) from the name of the
program binary.

This has been fixed in v2.002 of the client

You can improve performance and reduce clutter in your log file by running
a looping script that calls "rc5v2 -update" and sleeps repeatedly.  Then
the network access will be done in that copy of the client and it will keep
the buffers filled and ready for the other instance of the client.
