The best developed and most cross platform capable module for this in Perl is IPC::Run. I know Barrie Slaymaker pretty well (I speak to him usually every day), so if you get stuck with it, give me a shout and I can get you some help. IPC::Run allows you to basically feed a process with data as and when it can accept it. And you can do buffered reads on the data coming back out of it. It's a bit like IPC::Open2, but more like the mythical "IPC::Open3" (given that it allows you to also control STDERR).
