well, I thought I'd have a go!... and have actually had some success in getting shapes out of illustrator in to hype.
I did a bit of reverse engineering of the Hype doc (which is essentially a plist file) to find out where the shapes are stored. Thankfully, it still all works when the plist file converted to XML!. So I wrote an illustrator script to export path points as XML, then munge them in to the Hype document's plist file. Here's my progress...
Still a long way to go.
One issue is Hype's vector format doesn't support multiple paths in one vector shape. So every path in illustrator needs to come in to Hype as a separate shape.
The other issue, which is a dealbreaker is that Hype's vector shapes don't support compound paths / booleans.
I've also got to sort the control points properly. Almost there though.
And for whatever reason it's all upside down.
So it might be useful at least for solid shapes, but it's not really useful until Hype add support for compound paths and multiple paths per shape. I'm sure this is their stumbling block with development, not so much getting points and shapes across. And I guess when they do, they'll prob be able to import vectors then.
