There is an app called FoxFi. It works on some Motorola phones, but not all - does not explicitly mention the Droid 2.
The description says:
Enables WiFi Hotspot on your Android phone without a Hotspot plan from your carrier. No rooting required! Just install and turn it on. Currently works on most Samsung phones, some Motorola phones (Razr/Bionic/DroidX), LG Optimus/Vortex/Ally, ZTE N762, HuaWei Comet. Does NOT work on HTC phones or Motorola Droid.
Foxfi doesn't work on my d2g either. I get the Verizon wifi tethering web page. Clockworkmod tether is for wired tethering to laptop/desktop. Not sure if it will work with my xoom as I don't have a microUSB adapter.
