PC java pgm to/from AS400 RPG pgm

I'm working on an application where a user selects something off a 5250
display file screen which drops a message into AS400 Data queue on which a
Java app on the PC is waiting.

When the Java app sees the queue entry it takes a prepared URL from the
queue entry and launches a minimal browser. When the pieces are manually
started it seems to work pretty good and is quite fast. However that is 1
AS400 job on 1 PC.

Scaled up there will be 190 possible AS400 user jobs and 190 possible PCs.
To handle that I planned to have Keyed data Queue so each PC will know when
to launch the browser call.

Does that sound like it should work efficiently?

Will the fact that some of the PC's will be coming into the AS400 thru a VPN
influence the simple logic of what I've planned.

Is there a "slicker'er" way of having the PC Java app talk to an AS400 pgm
and if so how would 190 processes times 2 know who is talking to who? (not
using data queues that is)

I'm a Java newbie but there is an experience Java person working on the PC
side. He's only seen pictures of ISeries boxes however.
