Nobody posting so here are a few things to consider:
Doing it properly:
Whilst your proposed project will not be 'hardcore' it will raise 'adult content' issues...
It would be wise for your client to seek legal advice and to have a lawyer sign off for the work done before it's published.
ALSO:
Indemnities, content licenses, model releases etc.
BBFC classification for video and digital media.
Title 18 etc, for US compliance regs.
Legal - 'sign off' (as mentioned).
DON'T do it the way most do:
'Balls to the walls' - IE: Just go ahead anyhow...
Most UK site owners are unaware that their sites are illegal.
Especially DVD re-sellers and content site owners.
IMO - Just waiting for their asses to be fried...
