Well, I should have stated My Ultra-1/150... 

I haven't tested it on the other Ultras I have access to.

People ask for the features.  You may not read it here, but we see it on

Such as your question...

You should have no problems running the client in the same directory.
They will all use the same buffer file.  Locking? Yes, it does do file
locking, so it's not unusual (rather, it's normal and non-corrupting) to
see an client error such as Buffer is locked 1 - waiting 1 second...
Means that another client is either reading/writing to the buffer.

I've run the v2 clients on a NIS+ lan of 28 machines and had no problems.

An expected quirk - whichever client gets to the end of the in buffer will
do the -update, so that machine will get credit for the keys in the out
buffer... so you'll have machines show up in the stats with skewed rates.
