It is a very nice idea, I talked about it sometime ago when I saw http://www.thedjangostore.com/
Massimo is the copyrighter of the web2py brand and logo, so if he agree we can use http://www.cafepress.com/ for worldWide and local manufactures as www.vitrinepix.com (for Brazil) All the money goes to web2py project (it needs a web2py foundation?) Or, if Massimo agree, each one of us can use the same default image and build your own t-shirt on that sites. -- Bruno Rocha http://about.me/rochacbruno/bio
