I am sure that Jon or John will step in here and answer this. I have never had a seedpod on an Aeschananthus but have only seen pictures. I must say they fascinate me.
Here is a link to a seedpod that I think is ready to gather.
I sure hope the experts jump in here and help.

Jumping in.....its not that uncommon, especially if grown outdoors during the summer, where the hummingbirds do all the dirty work. But, they are very easy to pollinate with the aid of one's trusty fingernail. The pods are long and beanlike, hanging down. Some species can have pods over a foot long. They take several months and when ripe will dry and split open lengthwise. The seed then floats out. Unlike all other gesneriad seed, lipsticks will have seeds with tiny hairs attached, so that the mass of seeds looks like fluff. The actual seed is a dot in the middle of the hair. Some species have just one hair, some have two hairs, etc. They germinate like other gesneriad seed though. You just take a pinch of the fluff and press down gently on top of the surface of the very moist media and enclose. Your seedlings will look different from the parent in that as they grow their leaves will be a little different in shape and markings; but this is juvenile foliage. It is very rewarding to grow on the seed. You will learn so much, watching your seedlings grow and mature.

To harvest the seed, you can wait until the pod dries and cracks, and then quickly gather the seeds. If you see the pod beginning to crack or dry you can remove it and place in an envelope to capture the seed when the pod dries. But, even if you miss the event and the pod splits and dries, there is usually some seed that remains for several weeks or more. One pod will contain a lot of seed--enough to grow on several hundred seedlings.

I have a miniature lipstick plant that produces a seed pod on every flower, From what you said above I am going to just put the dried seed pod in potting soil and see what happens!!!!!
