In response to my previous post on aggregators, David commented:

Sounds like what you need is a client/server Remoting based aggregator set. Where you have a server running at home that downloads all the feeds, and then you have multiple clients that just grab the stuff.

Exactly. What I kind of had in mind was something that runs and collects whatever feeds I'm subscribed to. My first inclination would be a Windows Service, but since I most likely couldn't install this on my web host, I'd have to run my home PC all day, but whatever.

Regardless - this server, wherever it is, would expose these feeds (and any associated updates, such as marking a post as read or flagging it for follow-up) via a web service. The various clients would simply talk back to this service.

You know, I'm starting to get fired up about this. When I finish my other side project, maybe I'll actually work on this! It might not be overly useful to other people, but it would definitely simplify my life just a bit....

And to David and DataGrid Girl (and all others reading this) - thanks for reading! :)
