No, I have not taken a deep look at any particular ERP. 

But I do know that we create a lot of data that reside in silos, off-limits to analyses, simply because nothing talks to anything else. Okay, I suppose you could export to XLS, then import to another package, but that would get old. I would love for my agronomic data to interact with my financials. We really need a GIS-based ERP. I've not found anything like that yet. It's something that would be a fork on an existing ERP, I think. "If QGIS and ERPNext had a baby" sort of thing.
