Good idea. Some thoughts :
* as you say and as i have observed too, upstream is more keen on
  using embedded libs. I hope i'm wrong, but my guess is upstream won't
  be friendly with us, debian maintainers.
* libuv releases match nodejs releases (same versions)
* API is not stable. Good news is that it's C - we have tools to manage
  soname versioning.
* julia, nodejs and libuv are young and they will be hard to follow...
  at least until nodejs reaches 1.0 (upstream seems to be really trying
  to stabilize everything now).
* (not sure) i think latest libuv relies on unreleased fixes to libev.

Maybe we can start the work on packaging libuv, and depend on it when
it doesn't require heavy patching work and updates every month...?
