Currently the are not able to build in one command. I have to do that manually (my turnaround time is 12 hours, however, so this isn't a huge deal).

What can players do with the shops?
* Buy certain items at a certain price from other players
* Sell specific items at a price of their choosing

No shop needed for some other useful stuff that helps manage the shop, however:
* They can improve items to high qualities (something NPC vendors can't guarantee, or do most of the time)
* They can create their own items.
* They can easily undercut NPC on price and item quality

No shop is needed to engage in commerce, it's merely a way to facilitate money moving between PCs, that and some PCs make a big deal of their shops. One runs a Bar ICly and puts food and such in his vendor that PCs can buy (once again, undercutting NPCs on quality and price).

And Kereth: I'm removing high end items from vendors right now, leaving only the 'schematics' in (ie, plans to make advanced items), seeing if this helps those who make stuff out a bit. That's a longer term project, however. My daily economic statistics data shows no adverse effects, at the very least.
