The secure delivery protocol described above has been implemented for making source bookfiles available to special print houses, i.e. associations, libraries for the blinds, schools partners of the project. More than 150 professional users from around 100 organisations have been certified and thus have received login, password, and digital certificates. They may access around 2500 titles that are available from the server. These professional users can also use the server for uploading files they have adapted in order to share them with partner organisations. BrailleNet keeps the history of downloaded/uploaded files. These services are free of charge.
