Sorry about the delay, I was on vacation since this topic started.

Here is the command we use:

udp-sender --full-duplex --rexmit-hello-interval 700 --file
images/dell620.gz --min-clients 30

We had initially used the --rexmit-hello-interval flag due to
older hardware that wasn't always connecting on the first
attempt.  If you think it could be related to multiple
"press any key to start" prompts, we can peel it off.

I don't recall the exact udpcast version but the man page
shows June 22, 2006.
