Brief guide to adding user-defined transport plugins

[Shu]

Hello,

My goal is to make gRPC async server-client examples to work over a transport plugin that I would write myself, using libp2p, for example. This is the only thing I have seen thus far in terms of documentation: https://grpc.github.io/grpc/core/md_doc_core_transport_explainer.html

I have a few initial questions:

1. Is it possible to register my own plugin as a part of my own application? At which phase would this have to be done? Is there any example of this being done?

2. If the registration succeeds, it is possible that my custom plugin as well as one of the provided plugins (chttp2, for example) are both capable of handling transport layer responsibilities in a particular scenario. How could I decide which plugin gets chosen?

Thanks in advance!
