No, I believe Elbit was around at the March float test or before. Remember, the invitation to participate in Trident 2008 came before the CWID trials had even occurred. IMO, Elbit will be providing some of the radars/electronic devices which are to be included on the Sanswire airship(s).
In a show of cooperation and spontaneous integration, GlobeTel's HotZone(TM) assisted two trials by other invitees that were not able to connect to the HLS Network as planned. Using HotZone(TM), the two other entities were easily able to connect to the network and complete their trials successfully.
