Having been to many pen shows, it would require each vendor to list from a few hundred to several hundred fountain pens, pencils, roller ball and ballpoint pens and include pictures and descriptions of them as well as listing and photographing ink, paper, tools, parts, supplies and ephamera. Some dealers, such as Roger likely could do it as he is very organized and has a good inventory, but some are not so well organized would have difficulty, and it would take a lot of time to do it.
Now, the Pen Auction is a bit more manageable and by puting it on line good prices might be obtained, however it would mean getting an auction platform involved.
And, don't forget packing and shipping, not free and time consuming.
So, yes a Pen Show could be put online, but given the technology involved and the lack of the development of cheap, easy and seamless tools for online sales, it likely will not happen.
I am amazed at how little has been realized in regard to the online sales experiance over the last 20 years. It as envisioned to be an immersive experiance with the option to view products from multiple angles and receive highly detailed and accurate information regarding each product, linked in a suite to other products and able to be automatically and easily compared to product offerings from different vendors.
Instead we get an electronic version of competing vendor catalogs, with no automated system to compare and contrast product offerings from different vendors, little detailed product information and a few badly made two dimensional pictures.
