so an idea about physical payment token arised on irc,

main points
* keypad for pc independent pin code entry
* cheap 7seg screen for payment sum confirming
* prom for program memory(possibly a protected ucontroller) to guarantee uninfected device side software
* eeprom for wallet.dat(encrypted with decryption key only on prom with read disable keys switched on prom)
* some communications with pc to get payment data for user to confirm and to sysnc wallets

benifits
* protection against infected pc, private keys never leave the device
* over the counter payment

pitfalls
* even protected ucontrollers are suspectible to power use analyzis, and other grazy hackery eg like this http://www.bit-tech.net/news/bits/2010/02/10/tpm-security-cracked-wide-open/1
* nothing protects against http://xkcd.com/538/

here is a list of open source webshops

and here is a list of open source webshops supporting bitcoin(bitcoin modules available but not included in the official release)

Virtumart
Zen Cart
OpenCart
WP e-commerce

now its obvious that the true value of a currency is what you can buy for it, so to raise bitcoin value we must get more vendors to accept bitcoin
but that can never happen until webshop softwares start supporting bitcoin payments

now most of these software solutions are written in php, two in java and two in python, one of perl and one of asp .NET
so what we need first is a php webshop module to attach to half of these solutions

now i looked around a list of businesses accepting bitcoin and found few vendors use some of these widely used eCommerce softwares,
eg My Healthy Organics uses zencart a php based foss eCommerce solution
the thing is that Zen Cart featurelist does not include bitcoin payments as far as i can tell, so did the vendor write his own support for the feature?

i think we could get lot more vendors supporting bitcoin if we could get a "pay with bitcoin" feature from some of these sites on the list and get the feature included in all the most used foss webshop solutions

so is there any vendor here who has modified their webshop software and could we approach the webshop development teams with that solution?
