TaxPal would have to be branded/developed, which would in turn just send traffic to the .com. Tax season is over too (I know, not for businesses, but even Paypal wouldn't be as popular without personal accounts)
ArcadePal - I don't really see how those two go together. Would it be a product, like a quarter coin holder, or would it be a website with java/flash games?
TaxPal, low $xx
ArcadePal regfee-$xx
imho,
