Yes Rick although most of the nighshades are self pollinators some cross pollination occurs. Lycopersicon, Solanun amd Capsicum are very closely related genera If you look carefully their inner floral anatomy they are all very much alike. I just checked what my JC.Willis Dictionary of flowering plants says. about the Solanaceae= the nightshade familiy. The ovary has two separate locules (that is distinct bags) that harbor the ovules and the style has a two lobed stygma where the pollen sticks. Normally each grain of pollen that has stuck to the two lobed sticky stigma will start its germinative process by which a tube is formed that tries to reach an available ovule. At the tip of the cellular tube are the cromosomes . Once the tube reaches a given ovule then they merge and fecundation has occured and the formation of the seed embryo starts. Only one pollen grain of the many that try to reach each fertile ovule. In the case of the capsicums some have a three loculed ovary instead of two. When you open up a pepper you find the seeds clustered at the top and along lines fixed to walls. These lines are the placenta where the ovules stand before each becomes a seed. So in your above mentioned post, you are confusing the word ovule with the word ovary. The ovary is the lower female part of a flower and contains the female counterpart in the form of female cells called ovules as different from ovary. Normally once pollination / fecundation has occured the ovary develops in what is known as a fruit. It becomes fleshy and according to its reproductive strategy it will add juice cells, pigments and taste to tease disseminators to carry the fruit off somewhere( that is usually the case for berries like peppers, tomatoes and most of what we know in common language fruits). The ovary still contains in its interior the former ovules now transformed into seeds but almost in the exact position as they were inside the initial ovary. Only that now the whole organ starts growing into what we end up eating!
Tomatoes benefit from hand shaking when grown inside a greenhouse. Large commercial growers use some kind of vibration. They do not rely on insect pollination. the same is true for other indoor grown solanaceae ( peppers, eggplants). In the open there are more chances that some insects will cross pollinate and wind can carry pollen from flower to other. For that reason its best to keep sweet peppers distant from hot ones because they might cross pollinate. But as far as what I know hot descendants of sweet peppers will appear only in the following generation, not those simply pollinated by a hot pepper pollen. But usually nature has its surprises. In the link you mentioned capsicin appears in the placenta and not inside the seeds. Thus I must preclude that the hot part is in the ovary/female counterpart and not inside the pollen, which makes sense from an evolutionary point of view. I really haven't investgated what role hotness plays in the overall reproductive strategy of a hot pepper. Since cultivated plants are man associated and become cultural obligate associates some traits like hotness acquire adaptive advantages more due to the humans than to the original plants themselves. Cultivated hot peppers need vegetable gardeners that provide conditions to continue to grow and reproduce. I do hope that I explained it correctly.
in a four person size stew. Like all our food grown here these also are organic.
btw this holds true for any flowering plant in the world. You more than deserve to be explained. You're a good student!! 
I'm grateful that you insisted. I derive much pleasure in sharing what I learnt from others keeping and widening knowledge anywhere in the world. warmly Arturo
