Re: Custom EventList for huge datasets?

Hey Daniel. It is certainly possible to do this with a custom EventList, but
I don't think it's necessary to model it as one. I'd keep the parts of your
pipeline stock and write a "service" that you can ask to fetch data and dump
into your "standard" pipeline. That said, of course filtering and sorting
look much different than what FilterList and SortedList provide (maybe
they're just calls to your "service" to fetch new data?).

Just a thought...
