On my Droid X:
1 ) I set up the 3G hotspot app with security as recommended.
2) Installed and configured "Dazzle Configurable" from the Market. Configured it with the toggle for "Cellular Radio".
On my Tablet:
I configured the WIFI to see the Droid X network.
Open a browser and browse to any web page. I am re-directed to the Verizon sales page where it asks me to purchase the hot spot data package for my plan. (do not purchase)
On the Droid X:
I toggle off and then back on the cell radio using the Dazzle app.
On the Tablet:
Tray again to browse the web, and it now works, even though I did not purchase the plan, and did not accept any terms, etc.
Well, then maybe the hot spot is not acting like an ad hoc, because it sure does see it. When you go to the network setup screen on the tablet, it shows the droid x right there. Tap it, and it gives the option to forget, or connect. Tap connect, and in about 10 seconds, it is up and says connected. Can go to the market, browse pages with a browser, etc...
