Well more searching turned up some info. Because of liability stove manufacturers recomend using their fuel. The industry standard is EN 417. The rundown so far.

MSR Pocket Rocket Isopro cannisters are OK for the MSR Jetboil.
MSR Jetboil Jet Power cannisters are OK for "other" stoves.
No specific models were listed.
Snow Peak Giga cannisters are OK for MSR stoves.
Couldn't find any info for the orange colored Brunton cannisters.
