Sometimes you gotta share some text (or 64bit integer values) between instances of touch and the only option is Touch Out which is a little buggy and slower than Shared Mem. Seems like some low hanging fruit that would come in really handy on projects.
What bugs are you encountering with the Touch In/Out DAT?
I’ve run into firewall issues when using Touch In/Out on a single cpu when using multicast. I’ve also had numerous issues of Touch In/Out not working and I’ve had to cut and paste the TouchIn/Out operator for it to start sending again.
