=== Discussion ===
We had a lively discussion about IO Modules. The thesis so far is that the definition of an IO Module has not yet been clearly specified, and eBPF itself is too flexible and too open (many hook points, many use cases with different inputs, etc.) to the point that it is difficult to conceptualize the notion of a module. Simple tools such as the storage monitoring examples are okay and self contained. But a chain of IO modules that interacts i) between themselves, ii) with linux kernel components, will be difficult until we close the definition and remove some of the flexibility.

- create a proposal of 'net interface' and 'io module' to discuss within the mailing list
note: for now defocus some on performance, e.g. no high rate CP<->DP interaction
The idea will be to build up the initial concepts around the GBP use case.
Also, so far there is a concept of a host local module manager, comparable to libvirtd to networking, which holds the running modules and their relationship/connectivity to each other. A developer from PG with some spare cycles has been prototyping a GUI that would one day go on top of this rest API, which was demoed during this meeting. The code for this should go up on github before the next meeting.
