Definitely, There are tons of "wiimote guns" (little plastic jobs that just hold a wiimote) I can get for 4$ at Ross. If this would work, I'll pick a few of them up, steampunkify them and have a pair of dueling pistols for shooting games.
I did turn up one review from 3 days after it's release saying it was garbage, but then that review also said it doesn't support the sensor bar, which the BlueSoliel website specifically says it DOES support. I noticed they're up to version 1.01 though so it may have been that the initial release was rough.
