if the models you are shooting are going to be for their own site (solo girl site), or for a members area where you will be contiually shooting her or other models, check out this great retention tool for members that helps to add audio content:
http://www.mynaughtymessages.com
This is my dot-bomb technology coming back. The model can use a mobile phone to record a message about what they are doing now, shopping, day dreaming, bed time story, a naughty message, etc.. once they hangup, the message gets digitized into .mp3 format and uploaded to your site, so you own the audio. Unlimited message recordings for $100/year per mailbox.
Fight the and now back to your regularly scheduled thread!
