Hi All,

For those interested, I've been working on a formal analysis of DCs the
results of which should appear online in the next few days.
I'll post to the list when it's up.

In summary I managed to prove a server only version of DCs secure (i.e.
does not violate any of the properties in Appendix E.1) under the Dolev-Yao
model without resumption, and work on a more general result is ongoing.

Regards,

Jonathan
