A good way to convey a message from one PC to another is to have the sender of the message act out the contents of the message for the benefit of the recipients. You just need to be careful that the characters don't end up violating causality by having information flow back the other way.

Unless you're into that, of course. In fact, that could make for an interesting campaign. Just remember to break out your time travel rules.

Anakin: We should patch this through to the Jedi Council.
Obi-Wan: I've followed Jango Fett to Geonosis. Count Dookû is here, with the Separatist leaders.
Mace Windu: Are there any more jelly babies?
Obi-Wan: He has the Peace Moon plans. And it looks like the Separatists are planning to use Jango's clone army.
Obi-Wan: Anakin, assuming your business on Tatooine is done, join me here—
Padmé: As soon as we've finished our geological survey of Naboo!
Obi-Wan: —and we'll arrest Dookû and recover the plans.
Obi-Wan: That should be enough to get us reinstated to the Jedi Order.
Mace Windu: But if you fail we'll chop you in half!
Obi-Wan: Right... I'm glad I'm a recording and didn't hear that.
