Hi John,
installing Moodle 1.9 is easier than you think, so that would be my first recommendation if the HotPot module is important to you.
Finishing off HotPot for Moodle 2.0 is next on my list, after I am through with a writing job that is turning out to be more work than I expected. Bear in mind that it will probably need a few weeks of testing in thr field before I would feel i could confidently claim HotPot for Moodle 2.0 is "indistrial strength" in the way that HotPot for Moodle 1.9 is. Even when it is ready you will need to install it "manually", because it is not part of the standard Moodle 2.0 package.
Santa gave me book called "Getting things done" so maybe that'll help
BTW, my ToDo list is suspended for the day because I am in charge of the Xmas meal!!
season's greetings to one and all
and many happy HotPots for 2011
Gordon
