If you're not going to try to control the VI over the web, probably the easiest way to do this is to enable the Web Server that is built in to 6i, permit users to see it, and then use the .monitor? command to view it from a browser. You can set the refresh rate to 10 seconds with no problem. I'd go to www.ni.com and do a search on labview and web server. There is documentation on exactly how to set this up.
Good luck,
Mark
