Just received this email from H of L:
The report of the Committee will be published on Tuesday 5 February at 11am. It will be available from bookshops (the publisher is TSO), and on the web (www.parliament.uk). It will include a note that your own correspondence with the Committee will be available for public inspection in the House of Lords Record Office
Looks like there is an end to this affair in sight - here's hoping for the right result
