So you want to install Flash on the Droid?
It is still in beta, and not in the market yet, and you must have 2.2 installed.
Here is what you need to do, I just installed it 15 minutes ago, and now I can see other videos like from break.com and my Flash driven menu on my website.
First go here:

You will also need to visit the Market and install a free file manager called Astro.
After Astro is installed, you can either go the URL above on your Droid and choose download file, or put the file on your PC into a folder called flash_beta or whatever you want to name it.
I choose to put it on the PC fist, but either way will work.
You will need to go to your settings on Droid under Applications and check the box called "Unknown Sources" if you put the file on via USB cable or if you download it from the URL above to your Droid.
If using the USB cable, move the folder from your PC to Droid, then unmount Droid, then fire up the Astro file manager.
Navigate to SD Card and look for the Flash folder.
Find the file in there and push on it, then choose "open app manager."
It will then allow you to install the file.
After it is installed, be sure to go back to the main settings under applications and clear the check mark for "Unknown Sources."
Now go test it out somewhere that uses Flash.
