I am not sure if you are saying that with Penguin, if you have keywords in your domain name, would it be okay to have the domain name (e.g. [buildmetalwidgets.tld)...] or site name included in your signature or not?

IMO it wouldn't be OK unless you have have a number of other "natural" links with "natural" anchor texts.
