No comments?

Well to be honest I'm not super keen on either solution. But if nobody
else has any input, and nobody else has another workable/implementable
idea, I'll need to make a decision so I can get on with things.

I'm leaning on the side of the 'long running operations' approach [1].
For me, what tips the scale is the fact that it allows maximum
flexibility in the future.

Cheers,

Stef
