Hi Jouni,

do plan to support PrismGT in future. I would like to use all the features
of your 802.1X with PrismGT. If you do not plan to support PrismGT, what
do you think is easier ...

a) ... to port your hostapd to the Prism54.org project or
b) ... to port the Prism54.org project to your Host AP software ?
