Can we still plan to send them as job files, or do you feel strongly that these should be part of the message?

[jmchilton]

I think they should be part of the message - I like the API design better that way. I could be wrong though for sure.

In that case, how about we support chunking them? Probably not a bad idea as we want to support streaming while running for user feedback anyway (although sending the full stdout/stderr upon completion is probably safer than having Galaxy use the reassembled pieces).
