Javascript trust issue is a problem that's already discussed and evaluated in other area and context of w3c, there are several solutions on-going. This kind of issue is the same considered for Javascript encryption. Trusted javascript can be verified/loaded today trough plug-ins and by trusting the 'application delivery source', so that's not an issue. >From 0 up to 100 of security with Javascript you can stay at 0 or reach 100, depending on the way you deploy and use web. Imho making SDES SDP offer/answer available to Javascript it's a great achievement as it will be able to unlock the creativity of the technological ecosystem. People will probably manipulate SDP, sign it, re-encrypt it, pass it trough OOB channels via CORS or as many other options we may envision. -- Fabio Pietrosanti Founder, CTO Tel: +39 02 85961748 (direct) Mobile: +39 340 1801049 E-mail: fabio.pietrosanti@privatewave.com Skype: fpietrosanti Linkedin: http://linkedin.com/in/secret PrivateWave Italia S.p.A.
