Hi Thierry:

We didn't have this use case in mind when we did our initial implementation of heterogeneous instance types, but it's an interesting idea and should be pretty straightforward to implement (says the guy at ISI who probably contributed the least amount of code to the heterogeneous implementation...).  Is there community interest in this type of functionality?

Take care,
