Should be no problem. You can point to any local port, and you can run multiple "kites" at the same time (assign public names to mupltiple ports at once). Just make sure your apps generate relative URLs and don't contain absolute IPs and ports and it should be smooth sailing.
Thanks, I'll play with it. I have Friday demos for clients and I would love to not have the localhost:xxxx in the URL just for sanity's sake. Love the idea, cheers.
