Am I correct in assuming that this next "mini release" of J will allow me to access J on my Palm Pre phone, through the web browser on the Pre (or through any web browser)? Is J software going to host J access through a browser front-end, for testing?
My son & I have a business that requires web servers (caveconsulting.com), so I have access to a web server where I can host J, including the browser front-end. What would be involved if I wanted to set up up a hosted J "service" once the mini release is out? Skip Cave Eric Iverson wrote: > I was careless in my wording.
