I'll throw my hat in though I currently do not have a portfolio site. I have been in house with SIC Cash and PimpRoll (both remotely) and more recently did a stint in house with AEBN. I have also done the mainstream thing and was the Creative Director for TrustSoft in Houston once upon a time.
I have been doing adult design since 1997 and have a solid client base and references. As I don't have a formal portfolio online I will save everyone the grief of posting link after link.
