I see this as useless for the following reasons:
1. IFC is already the file format with similar capability + its open source, not vender specific as SAF is, and if you went to buildingsmart site, you will be able to see more BIM + CAD programs that can import and export IFC files. while SAF is only accepted by 10 program vender as maximum.
2. Most of the MEP equipments and connections are govern by the spaces they serve, and by the requirements of local regulations, so either way you will have to export project's spaces configuration and distribution, which would be either by using the original program's file, or through IFC ....
If you're going to use original files, then there is no need to use SAF, as the two programs will be able to communicate with each other directly, and if you're going to use IFC, then again you don't need SAF for nothing, since it's already exporting the geometry and data not only of the equipments but everything (almost everything you're using).
3. Then again you insisted on the point that equipment's node would carry the data for MEP connections, and again I tell you, I quick checked SAF site,
and I couldn't find information about MEP what so ever, but it had information on structural connections, so
SAF NEEDS TO INCLUDE MEP NODE SPECIFICATIONS FIRST, then the other programs to ADOPT IT, to make your idea viable.
You simple can't put the cart before the horse
.
4. I´m not familiar of different MEP design, calculation and modelling programs, except for Revit & CYPE, and both from my point of view can handle the data exchange with ArchiCAD using IFC, which will include geometry and data, cause in that case, you will have a combination of IFC project models (Architectural, Structural, Engineering), and in that case with an 80% of certainty, who ever made the Architectural model will not model the MEP system in ArchiCAD, and even then exporting/importing an IFC of the required model would do the trick.
5. ArchiCAD should set a number of reserved parameters for MEP, and right now, what is available is too low, and if we are going to talk about Electrical Equipments the shortage is stark.
A good friend of mine have once told me that I´m so brute that I´m capable of creating a GDL script capable of creating GDLs.
