It became an important point at Lynx, so Patrick from Lynx (or a another assigned colleague) will get in touch with you to sort this out. I already discussed the solution proposed by you (therefore forwarding the e-mails below) and we see no technical problem with implementing like this. Pls keep me in the loop as I would be interested in the final implementation as well, for the purpose of my project.
