I too have been doing some promotion.

Perhaps a student will show up and just do it.

I put out a request to various open source funding agencies but none
have got back to me as yet. I agree libcurl is a good choice for C,
and I very much would like to extend the concept to "finding the
bloated link" via dropping the ttl during the test.

So my tool is tentatively called "wtbb" - Where's teh Bloat?". WTB =
want to buy but wtbb.org is available.

I perhaps foolishly decided, however, to attempt a rust version first,
leveraging the tokio library. Finding a way to put in hooks to the
various parts of the process (or rather, threads) has proven hard
(curl has all the right hooks for each phase of the SSL neg), but it's
really amazing how much you can accomplish

https://github.com/seanmonstar/reqwest has some examples.

Ideally I wanted an infrastructure that would ultimately do quic (http/3), like
