Brent: Would it be a good idea to target those objects with (active) jets?

Dave: Definitely! Though on our previous two runs we focused on known binaries (of which there weren't many, it was before your big OGLE paper), and particularly those with low surface brightness to lessen any nebular contamination complications. We are currently expanding the programme to also cover suspected binaries, and as such PN with visible jet structures.

Brent: Sounds like alot of fun. Are you aiming to find the same sort of signatures as 2006A&A...454..527G did for VV 47? Are they really distinct from other pulsations?

Dave: First question - yes, that is what we are after. Second question - In all honesty, I don't know! This project is still very much in it's infancy, mainly due to bad weather affecting our observing runs. This has resulted in us only performing a rough reduction whilst at the telescope. Hopefully, should we be allocated time in the next period (Jul-Sep), we will be able to obtain a couple of complete data sets and properly begin the analysis.
