We currently have an SG5 meeting scheduled on April 1.

Do we have an agenda? Or should we cancel?

My impression is that P2066 (on the Prague wiki) is in good shape for SG1 approval. Given that the Varna meeting has been cancelled, we should aim for that SG1 discussion to happen during an SG1 teleconference, if possible. That might also allow the other participants here to be involved in any discussions. AFAIK, procedures are in flux, and this is not SG1's top priority, so I'm not sure how this will play out.
