There's a wordpress front end that is currently being developed that will allow people to pay via any currency (I think) that BitShares supports!
There's some info here: https://steemit.com/bitshares/@apasia.tech/woocommerce-bitshares-gateway-plugin-staging
It looks like it is being made by a Steemian!
Looks interesting. :) Beyond my technical knowledge and Wordpress though :)
Good luck!
