Need: XVNC. Selenium. Browser. Maybe app server.

XVNC and Selenium may be on a remote host (for simplicity, require same remote host)

$app_run_command -> script/myapp_server.pl -p 3000
$app_host_port -> ${hostname}:3000

Start xvnc -> vncserver :${disp} or ssh user@host vncserver :${disp}
Start selenium -> DISPLAY=:${disp} selenium-rc -port ${port} or ssh user@host ...

Kill xvnc -> vncserver :${disp} -kill
Kill selenium -> GET http://${host}:${port}/selenium-server/driver/?cmd=shutDownSeleniumServer

allow suppling of $remote as 'user@host' to populate ssh command -and- $host for selenium kill
