I un-broke DNS on my server so emails now send. I apologize for the flurry of emails, Peter has three tunnel end points and I forgot that my trigger operates on rows [0], so even though I did a single UPDATE it called the trigger function 3 times. I think Peter got 9 emails out of that, so don't feel as bad as him. :) -brian [0] - This is the only way I can get the changed data to pass along to the python script.

To be honest my experience with clustering is limited and generally specific to satellite based configurations. In this case I may make the VAX a satellite of the Alpha with the local disk acting as page/swap. Am I right in thinking then that the relationship changes somewhat in that the Alpha will always need to be up but the VAX can come and go as it pleases (with the correct shutdown sequence)?

I suppose if I do some hackery with iaxmodem, reconfigure my PBX, and do crazy crap there at low baud rates I could handle it. I hope you can automatically bring a line up at 1200 baud. ;) I need more raspberry pis to use as iaxmodems. Yeah no problem, the GSM operators modem pool will happily accept a 1200 baud connection and send it along as GSM data to my DECserver..
