Just incorporate man... no one has to know what you do.
Focus on the mainstream under a different entity... it's easy.
I've done a lot of mainsteram programming for high profile clients before I got into porn. My old bosses even know I left to pursue adult, they still try and throw some contracts at me.
If you got skills and aren't a murderer/felon, you should be able to get any mainstream job you're qualified for, just DON'T put your adult URLs/work in your resume
