Right now, it's a bit tedious to do as you'll have to dig out the dependencies manually. While a save/export to X function probably would be the easiest and quickest way to handle it, I would more like to see a library/dependency manager inspired by the Processing kind. Ultimately with a few additions that could make financial sense for Vuo and the community as well over time.
I at least swap out computers relatively often, so having Vuo linked to my account, logging in, and automatically pulling all my compositions and dependencies would be fantastic. Adding to this backbone is the possibility for creating a platform that will be beneficial for both team Vuo, contributors and users.
If you have 4 categories; Official // Pro // Community // Private, it should cover most of the bases. This way, the editor would also be able to be separated from node development in itself, making for a more continuous development/upgrade cycle. Instead of a base and pro version as it is now, you could pick and choose which (pro) features you need. Giving contributors a way to earn money if they wish would give an incentive for developing for Vuo - perhaps with a vetting process to list it in the official or Pro category. This could also ease team Vuos workload on much sought after node sets, and free up time to do core functionality/efficiency if external developers can see they can get something out of it.
I know that the option for an in app "store" would seem appalig for some, as the VJ/Creative coding communities at large are based on a huge effort of sharing, creativity and openness. On the flipside of that though, is the ability to actually put money back into the community and the application as opposed to a third-party store (that inevitably will come when Vuo grows large enough) which puts nothing back into the community or application apart from "exposure".
This may have gotten a bit more philosophical than intended - but if the ideas about this are in its infancy, it's well worth to think about.
Just a simple side note; instead of going the enttec route if you need a node, Elation has a pure Art-net 8-universe node that is a lot more bang for the buck. The eNode8 Pro has 8 DMX in- or outputs (per port configurable) for about the cost of 2 enttec nodes (street price). This reads a lot more like a sales pitch than I'd like, but we got two earlier this year to work with our MAs, and they have played nice all summer.
